[Page 8] Chapter Introduction MyLab 70 and MyLab Gold Platform (now indicated all as MyLab ) are a multipurpose ultrasound system designed to perform radiology, cardiac and vascular exams. It has several operating modes and several probes formats through either standard features or optional upgrades. MyLab design is based on the use of modular, functionally isolated printed circuit boards (PCBs) and subassemblies known as Field Repraceable Unit. This modularization greatly simplifies on-site service and repair. In most cases, on-site maintenance is accomplished by removing and replacing the PCBs or subassemblies. According the type of system and its configuration, it can offer the following features: B-Mode Imaging (Bi-dimensional) M-Mode Imaging (Mono-dimensional) Pulsed Wave Doppler Continuous Wave Doppler ECG Digital FFT Color flow mapping TEI X-RES Archive to store images (Biolab) The instrument is fully integrated and can be upgraded to a complete range of clinical applications. Operating modes MyLab displays ultrasound information in several operating modes. The modes available to the user depend on the option installed on the system and the probes used. 2-D Imaging mode In 2-D imaging mode (called also B-Mode), the system displays a two dimensional image of the tissue that lies within the scan plane. Because the 1- 1

[Page 9] system displays 2D images in real-time, the motion of the organ can be observed. In B-Mode the depth and the field of view can be varied as well as the frequency and the processing of the image in order to provide more information contents for greater diagnostic capability. Spectral Doppler modes Doppler capability allows monitoring blood flow through vessel or within the heart. In spectral Doppler modes the system graphs both the direction and velocity of blood flow on a spectral display. In pulse Wave Doppler the user selects the vessel of interest by positioning a Doppler cursor within the 2D image. Pulse Wave Doppler displays velocities within the range bounded by the Doppler gate on the cursor. The unit can simultaneously display the B-Mode image and Doppler spectral information, or independently display Doppler spectral information. The Continuous-wave (CW) Doppler, the simplest mode, receives flow information from all the moving reflectors in the path of the beam (selected on the screen with the beam line) and is not depth selective. Therefore, CW Doppler is able to provide the V max (the maximum velocity through the sample area). Pulsed-wave (PW) Doppler, in contrast, cannot be used for higher velocities. Color Doppler Imaging Mode Color Doppler Imaging mode allows real time spatial visualization of the blood flow velocity patterns in the vessels. Color Doppler information is displayed within the B-Mode image. Blood flow towards the transducer appears in one color (Red) and flow away from the transducer appears in another color (Blue). The color representation is an estimate of the mean velocity at the sample area. The equipment can combine Doppler to display B-Mode, Color Mode, and Spectral Doppler information or B-Mode, Color Mode and M-Mode information at the same time. M-Mode In M-Mode the system displays a graphic representation of the selected line of interest within the B-Mode display. M-mode displays a graph that shows how the line selected changes over time. 1- 2

[Page 10] Following basic precautions Servicing the system shall only be conducted by Esaote trained service provider. Lethal voltages are present inside MyLab . Use caution when opening the unit. Always consult the User Manual for proper use and operation of the system. The system requires proper care and cleaning. System care includes periodic inspections, cleaning and sanitizing the system. Transducers require proper handling, care and cleaning. Transducer care includes daily inspection, daily cleaning, disinfecting and sterilization whenever necessary. In particular: • Do not drop the transducer. Dropping the transducer against a hard surface can damage the transducer elements and acoustic lens and damage the electrical safety features. • Do not use a broken transducer. It may present a danger of electric shock. • Do not pinch or kink the transducer cable. If the transducer housing becomes broken or if there are cuts in the cable, the electrical safety features of the transducer could be compromised. When the system has to be moved, move it carefully. In particular pay attention when moving it along inclined passages. Observe the following precautions when moving the system. • Turn the system off and disconnect the power cord and any other cord. • Remove all the probes and place them in a safe place, or at least, be sure that the transducer cables are away from the wheels before moving the system. • Unlock the wheels before moving the system. • Do not allow the system to strike walls or doorframes. Identifying Boards type and revision Printed circuit boards are identified by board type, part number and Index of configuration (IC). The board type indicates the board’s major function. The type is abbreviated into few letters acronym. 1- 3

[Page 11] To each board is assigned a code, that is the part number of that board. The Index of configuration indicates the level of revision, both software and hardware. When new modifications in hardware or software of PLD components of the boards will be introduced, the number indicates in the label of figure 1 will increase. Every modification to the IC will be communicated from the Service DPT. Figure 1 All these data are written in labels placed on the board. 1- 4

[Page 17] Control Panel Assembly Orientation System closed This assembly can be laterally position oriented to maximize operator comfort; also, it can be tilted toward the back of the system for optimal maneuverability (closed position). These two rotations are controlled by locks located below the control panel (as shown in the drawing below). The anterior locking device is used to rotate the assembly into its optimal working position: when pushed, this device allows lateral rotation of the assembly (i.e., control panel and display). The posterior lock is used to rotate the assembly by 180°, so that the handle moves to the rear of the system, for optimal transportation. To the right of the locking device a lever allows to lift or let down the keyboard.

[Page 18] How to install the system At the examination site, place the control panel assembly into its working position (unlock the posterior locking device and rotate the assembly by 180°); unlock the anterior wheels (green levers) for final position adjustments. Check that the correct options line voltage (fuses on the power supply) is set. In units where it’s present the manual switch to set the line voltage, before turn them on check that it’s set to the correct line voltage. Once the unit is on check also the Video Standard one.

[Page 26] How to check the system and control the standard quality To verify the level of performances, the following procedures are requested: • Looking for the standard • Setting the monitor • Control the imaging quality: lateral resolution, axial resolution with • Control contrast resolution • Control Doppler sensitivity • Control Color sensitivity Looking for the standard With CA621 probe connected and located on the probe holder, turn ON the power, select the GENERAL preset. Set the system in the following conditions: 1. General Gain MAX 2. TGC Gain MAX 3. Doppler Gain MAX 4. Color Gain MAX 5. B-Mode angle MAX The image shown should not present the following problems: a) Random spike b) Black shadow cone c) High level of background noise In Doppler mode the spectral display should not present: a) Fix white tone b) White spurious signal c) High level shift noise In color mode set the box in the lower part of the imaging. In the box the color should be displayed with: a) Multicolor imaging, without random vertical spike with different intensity b) The colors have to be only in the box and not out of it. 2- 15

[Page 27] With 2D image only put the image at the maximum dept and angle, and select only one focus (the deeper). Using a thin blade with thickness about 1 mm, move it on the external surface of the array’s transducer see next figure. At the same time on the monitor will appear a white shadow cone. This shadow must be continuous from the beginning of the array to the end. See next figure. Put the probe in the probe holder, than look the image on the monitor, in this condition, you have to see the ultrasound image as shown in next figure. 2- 16

[Page 28] Control the imaging quality: lateral resolution, axial resolution with The most important feature of an ultrasound device is to show in the clearest way the reality of the organs under examination. This capability depends on the various resolutions of the system. Phantom overview The phantom is made of tissue mimicking gel and provides an effective means of monitoring the image quality of an ultrasound system. Ultrasound systems can be checked easily for linearity, axial and lateral resolution, Doppler sensitivity, color sensitivity and depth-marker geometry. In order to check the image quality it is necessary to have a phantom. In next figure there is an example of an ultrasound phantom. Positioning the probe on the phantom • Connect the probe LA 523 to MyLab Gold Platform and switch it on. • Put the image Gain at the medium level. • TGC control at the medium level. • Place with a probe holder the probe on the Phantom. An initial scan of tissue mimicking phantoms is done in order to adjust the receiver sensitivity controls properly. 2- 17

[Page 29] This should be set so that a uniform grey scale texture is obtained as far as possible into phantom. Before starting the trial it is necessary to check if the Phantom is properly oriented. Proper orientation includes: a) Be sure that the image plane is parallel to the sidewalls of the b) Adjust the scan plane tilt so that the image plane is perpendicular to the reflectors in the phantom. Tilt adjustment may be done by maximizing the echo signals US imaging originating from line reflectors situated in the focal region of the transducer beam. Meaningful tests of both Axial and Lateral resolution require more pertinent procedures, since measurement results are a function of sensitivity control settings of the instrument. The target of the resolution tests is to obtain measurements with sensitivity controls (TGC) adjusted to some standard level greater than the level usually required for obtaining good normal images while scanning. The Nylon line reflectors in the phantom are used for this test. The Phantom’s reflectors are attainable at the sensitivity level to which they are just well discernible on the display. In order to verify the axial resolution, it is necessary to distinguish at least two reflectors on the ultrasound beam propagation axis, with the quality shown in next figure. 2- 18

[Page 30] In order to verify the Lateral resolution, it is necessary to distinguish at least two reflectors targets which are perpendicular to the propagation ultrasound beam, the quality has to be as shown in next figure. Control contrast resolution The contrast resolution is the capability of an ultrasound system to recognize two near zones with different acoustic impedance. The concept of similarity is concerned when there are two areas with similar structures; similar structures mean similar acoustic echoes when hit by an ultrasound beam. The best the contrast resolution the best the capability of the system to recognize reflected echoes at a very low intensity. For this control it necessary to follow this procedure: • Switch on the MyLab unit. • Connect a probe to the unit • Select the Image Gain and TGC control at the medium level. • Select the maximum number of focuses. • Move the focus in the area where you want to perform the image. For this test it is possible to use The RMI CONTRAST PHANTOM. Instead of using phantom contrast resolution it is possible, in order to evaluate if the system is working well, to produce by you an image of the liver and the nearby parenchyma. Only by personal experience it will be 2- 19

[Page 31] possible to evaluate if the system that you are using is correctly set (in next figure an image on phantom) Control Doppler sensitivity • Switch the unit on. • Place the probe on the Doppler Phantom using a probe holder. An initial scan of tissue mimicking phantoms is made in order to adjust the receiver sensitivity controls properly. The receiver sensitivity controls should be set in order that a uniform grey scale is obtained as far as possible in the phantom reflector(s). Before starting with the trial it is necessary to check if the Phantom is properly oriented. The Doppler sensitivity test must quantify the ability of the system to detect ultrasonic echoes originating at a certain depth. A very good estimation of the sensitivity can be determined under clinical evaluation. Basically this test entails scanning the phantom's 45 degree angled simulated blood vessel at different depths and watching on the monitor the Doppler level at different depths. The sample volume test is the accuracy by which a Doppler unit places an electronically generated video gate on a region of interest. Moving the gate while scanning carries out this test. 2- 20

[Page 32] A properly functioning Doppler unit will detect very little Doppler signal when the gate is positioned outside the region of interest of the image that corresponds to the vessel's lumen. Another possibility to check the Doppler , is to find the Doppler spectrum on a finger ‘s vessel. In figure 45 is shown the result of this kind of check. Next figure XX shows how to find the finger’s vessel in order to perform the Doppler scan. Control Color Doppler Sensitivity The sensitivity in Color refers to the instrument's ability to extract the maximum flow information from echoes and to allow the clinician to visualize the flow from the physiological point of view as well. The system must accomplish to two important tasks, which are: reliability and accuracy, in faithful relationship to the B-mode image and body's anatomy, without introducing any artifacts at all. Sensitivity refers to the quality of B-Mode and Doppler information within a certain range of depths allowed by the ultrasound beam penetration at a given frequency. The evaluation of the Color sensitivity is acquired by referring to a personal experience method. For an Ultrasound system it is more difficult to detect the low flow velocity; therefore for detecting the Color quality a little artery is suggested. 2- 21

[Page 33] After connecting the unit with a High Frequency probe LA 424 try to visualize the color on your artery coming from a finger of your hand , and as a result you will have to see a good image with an artery dimension of 2-3.mm. To achieve the previous results, it is necessary to set the system in the following condition: • Set the Color gain around 100 (+ 5) ; the B gain around 180 (+ 10) ; the TGC at the medium level • Set the minimum depth • Set the B frequency at 10 MHz ; the CFM at 8.3 MHz • Set the PRF at a value of.2.5 kHz • Set the box window size according to the purpose. On the monitor you will find an image that can be compared to the following 2- 22

When it will be necessary to connect the line voltage to the unit, it will be specified in the notes. PROTECTION AGAINST ELECTROSTATIC DISCHARGES Opening and servicing MyLab it’s necessary to keep attention to the electrostatic sensible devices. In the unit are contained several boards and single components that can be damaged with electrostatic discharges. In the chapter 10 are listed all the sensible parts and are indicated the procedures to handle them. 3- 1

[Page 35] FIRST ELECTRICAL CONNECTIONS- PERIPHERALS ELECTRICAL CONNECTIONS To start the unit it’s necessary to connect the power supply cable and to turn on the main power switch on the unit. They are positioned in the lower backside of the unit (see next pictures). Also it’s necessary to connect the supply from the Mains Power group to the SPS. This is possible due to one auxiliary plug on the system, which supplies the SPS. With one electrical cord the system’s auxiliary plug is connected to the plug on the SPS board and sends to this board the line voltage (115 or 220 Vac). All the plugs are accessible from the backside of the unit. Main Main switch unit’s plug Figure 1. 3- 2

[Page 70] Chapter Block Diagrams This chapter will explain the block diagrams of the MyLab 70 and MyLab Gold Platform boards, in order to permit to understand all the functions that each one performs. System Block Diagrams In the next paragraphs, will be described the block diagram of the whole MyLabGold Platform unit, to explain easily all the interactions that are present among the various boards. In the block diagrams, the functions are gathered to permit an easy comprehension of the block functioning, which indicates the correlative electronic boards. MyLab Gold Platform Block Diagram In Figure 1. there is the block diagram of the unit. At the start-up the PC and the boards starts in parallel: the PC will start the Win XP sw and the unit will start the test and program of the various boards. As soon as the unit starts, the BLC and the IMC start to check the boards present, the HW version and if there are errors. The BLC make this operation on the back end (DIP, DCP, BSC, DEP) and on the IMC. After this operation from the BLC, the IMC will program the ITRs, the ICC and the ICS. When all the operations are completed the probe s election menu will appear on the screen and the unit will start to work.. 4- 1

[Page 71] The ICS is the board where are connected all the probes; on board there are four zif connectors and one round connector for pencils. The ICS receives the transmission data (bangs) for the probes from the ITR and control signals and settings from the IMC. In the ICS doesn’t arrive the high voltage to generate the bangs, this operation is performed on the ITR in parallel, so the ITRs send to the ICS already the high voltage signals. The ICS doesn’t perform any elaboration on the bangs or on the data received from the probes, but simply it sends the US data from the probes directly to the ITR. The ICS sends the information about the probe connected to the IMC. The ITR are twelve boards working each one in a little portion of the image (little vertical areas not consecutive). They generate the bangs (they receive the high voltage from the power supply) according the settings and the probes connected. The US data from the ICS are managed in the same way (every board manages little vertical areas not consecutive). On the ITR the data are filtered, transformed from analog to digital and the focalization is performed. The data are also amplified according the gain selected by the user. The IMC controls all the operations performed on the ITR and on the ICS. It sends to the mentioned boards all the necessary data (focalization data, gain, timing to acquire images and to generate the bangs). It receives the information about the probe connected and sends it to the PC (in order to show it on the screen). The US data from the ITR arrives to the DIP. This one performs other filtering and different elaborations for the US modalities BW, CFM and PW Doppler. From the board exits the BW data directed to the BSC and the I and Q components (in phase and quadrature for the CFM and PW) directed to the DCP In case of particular post processing elaborations of the image, from the DIP the BW data arrives to the DCP and, from this board (without any other elaboration), arrive to the DEP. 4- 2

[Page 72] The DEP performs only post processing elaborations for the BW signal, according some particular formula. The data elaborated are sent to the BSC. When the DEP works, the direct communication DIP-BSC is not active, vice-versa when the post- processing is not working, the DEP is not involved in the management of the BW image. The CW Doppler for the electronic probes is managed by the ITRs, which generate the bangs and send them to the ICS. The CW signal received from the probe returns to the ITRs and then to the ICC (clock and CW generator), where it’s processed (filtering, gain….) and where are generated the two components I and Q (in phase and quadrature). The I and Q data (analog signal) are sent to the DCP. For the Pencils, the bang is directly generated by the ICC which sends the signal to the ICS. The data from the Pencil probe returns to the ICC, where it’s processed in the same way of the electronic probes. The IMC controls all the processing also for the CW and send all the right settings to the ICC (gain, filters…). The ICC generates also all the clocks necessary to the unit. The BSC is the scan converter and the CINE memory. It receives the BW data from the DIP or from the DEP and stores them in internal memories, ready to be sent for the next steps. Also it receives the ECG signal (from the PSE) and mixes it to the BW image. It controls also the ECG acquisition. The DCP receives the I and Q signals and generates the CFM image or the Doppler trace according the mode selected and the setup of the user. After the elaboration the data are sent to the BSC for the scan converter For the CW Doppler, the signal before is converted from analog to digital, then processed as for the PW. The audio trace for the Doppler is directly sent to the PVA board (inside the PC group) where it will be managed. 4- 3

[Page 73] The BSC receives also the CFM and Doppler data (both PW and CW) and mixes them to the BW image (B and M) from the DIP and with the ECG trace (in case it’s present). Also for the CFM and Doppler the cine memory is inside the BSC. The US video image, which is produced by the BSC, is sent to the BLC In this board the US data receives post-processing elaborations (palette BW, CFM…) and then are sent to the PVA (board inside the PC group). The PVA will mixes the overlay (from the VGA board of the PC) with the US data from the BLC and send the result to the monitor. It also receives the audio signal from the SoundBlaster, in the board is amplified and then is sent to the speakers. The PC motherboard receives the command from the keyboard group, it transfers them to the PLC which sends all the commands to the BLC and from this unit to the rest of the system. The Figure 2. is the block diagram of the PC group. The mentioned parts compose the power supply group: the main power switch group, where there is the main switch of the unit, the insulation transformer and the unit fuses. On this group there are the auxiliary plugs for the external peripherals and the monitor. From this group the AC voltage (220V or 115) arrives to the SPS board where the AC line voltage is transformed in a 15 Vdc. From this voltage (inside the SPR and PSE) will be generated all the other voltages of the unit. The SPS also generates the supply voltage for the fans (variable from 7 to 15 Vdc according the temperature). This 15 Vdc is sent to the SPR and PSE. The SPR is the board responsible to generate all the voltages necessary for the unit: +5Vdc, +3.3Vdc, + 6Vdc, + 12Vdc, the high voltage for the bangs….. They are sent to the various boards. 4- 4

[Page 74] The PSE (which is positioned inside the PC group) receives the 15Vdc and generates the necessary voltages for the PC, the HDD, the keyboard group and the Display group. Also on this board there is the ECG part of the unit. On the PSE there is the ECG plug to connect the ECG cable to the patient, the data from the PSE arrives directly to the BSC. The BLC and the IMC control the output voltages of the power supply group. The Figure 3. is the block diagram of the power supply group. The keyboard group is the interface between the user and the unit. All the communications from/to the keyboard group are through the display group, which works as interface between the keyboard and the PC motherboard. The display group has a display on board, where are visualized some parameters (different according every modality) selected and modified by some switches and encoders on board. 4- 5

[Page 78] System Block Diagrams In the next paragraphs, will be described the block diagram of the whole MyLab 70 unit. In the block diagrams, the functions are gathered to permit an easy comprehension of the block functioning, which indicates the correlative electronic boards. MyLab70 Block Diagram In Figure 4 there is the block diagram of the unit. The way of working of te MyLab 70 is the same of the MyLab Gold Platform so the steps are the same. The differences are: -different ICS (with only 3 connectors for electronic probes) -different type of ITR board (but they work in the same logical way) -DEP board is optional. When the DEP is not present the US signal arrives directly to the BSC (sent from the DCP). -different SPR (it sends out different voltages) -the PC group code 9102572100 is optional (it makes a module with the DEP) For the description of the MyLab 70 block diagram it’s possible to follow the description of the MyLab Gold Platform unit. 4- 9

[Page 79] Figure 4. 4- 10

[Page 80] BMB (9501103000) The BMB board (Bus Mother Board) is the physical motherboard of the unit. On it are present the connectors for the various boards. No active components are present on the BMB. The tracks where the data are exchanged among the various boards are directly wired in the bus. ICS MyLab Gold Platform (9501087000) The ICS (Input Connector Switch) is the interface among the probes and the rest of the unit. On the ICS are assembled four connectors for electronic probes and 1 for pencil probes. The board doesn’t perform any elaboration on the US data from the probes and on the bangs, but simply passes/receives them/from to the ITRs. In fact the bangs are already received at the high voltage level from the ITR and are directly sent to the right connector. On board there are some relays which send to the connector selected the bangs from the ITR. The information about the probe connected is sent to the IMC. ICS MyLab 70 (9501087100) The ICS for the MyLab 70 (Input Connector Switch) is the interface among the probes and the rest of the unit. It works in the same way of the board for MyLab Gold Platform, but it has three connectors for electronic probes and one connector for pencils probes. The board doesn’t perform any elaboration on the US data from the probes and on the bangs., but simply passes/receives them/from to the ITRs. In fact the bangs are already received at the high voltage level from the ITRs and are directly sent to the right connector. On board there are some relays which send to the selected connector the bangs from the ITRs. The information about the probe connected is sent to the IMC. 4- 11

[Page 81] ITR MyLab Gold Platform (9501089000) The ITR (Input Tx-Rx) is the responsible about the bang generation and about the focalization of the signals from the probes. In the unit there are twelve ITR boards. No difference among them: every board can be seated in every ITR position without trouble. From the IMC the ITRs receive all the focalization data and, according the probe and the preset selected, they generate the high voltage bangs, starting from the low signal bang (also generated inside the ITRs). To perform this operation, the SPR sends in parallel to all the ITRs the high voltage to generate the bangs. When ready they are sent to the ICS and then to the probe. Every ITR manages little vertical portion of the image, not consecutive. The data from the probes directly returns to the ITRs. They are filtered and amplified according the gain selected, then converted from analog to digital. The digital data is stored in a memory ready to be sent out for the next elaboration. The ITRs doesn’t send the data directly to the DCP for the next elaboration, but every board sends out the data to the next ITR. So the ITR1 will send out the US data to the ITR2; there the board will add the signal of the ITR1 to the signal of the ITR 2 and will send all to the ITR3 and so on. Only the ITR 12 will send all the signals to the DIP for the next elaborations. For the CW Doppler for the electronic probes, the boards will create the bangs and will send them to the ICS. In the same way as before, every board will manage a little portion of channels in transmission and reception. The data arriving from the probe are amplified and sent to the ICC for the next elaborations (still as analog signal). ITR MyLab 70 (9501090000) The ITR (Input Tx-Rx) is the responsible about the bang generation and about the focalization of the signals from the probes. The ITRs for the MyLab 70 and Gold Platform works in the same way from the logical point of view, but the amplifier for the US wave are different between the two models. For this reason it’s not possible to mix the boards among them and to use the ITRs for Mylab 70 in the MyLab Gold Platform and viceversa. 4- 12

[Page 82] The board description is the same as for the previous model. ICC (9501091000) The ICC (Input CW-Clock) is the responsible for the management of the CW Doppler and for the creation of all the clocks of the unit. Starting from a single oscillator, the unit generates all the necessary clocks. The signal from the oscillator enters in one FPGA controlled from a flash memory and this FPGA generates all the clocks. From the FPGA they are sent out to the various boards. For the CW Doppler, the boards works in two different ways for Pencils or for electronic probes. In case of pencils the board generates the bang which is sent directly to the ICS. The CW signal arriving from the pencil is filtered, amplified (also according the gain selected from the user) and then sent out to the DCP for the next elaborations. In case of electronic probes, the board receives the signal from the ITR. This signal enters in a delay chain in order to be focalized, then it’s filtered and amplified (as before, also according the gain selected from the user). After these steps, the signal is sent out to the DCP as for the pencils. 4- 13

[Page 83] DIP (9501093000) The DIP (Digital Imaging Processor) is the responsible for the creation of the BW image and for the signal in phase and quadrature, necessary to generate the CFM and the PW Doppler. The data arriving from the ITR are filtered, then the ultrasound data are divided in case of e BW image (2D and M-Mode) or CFM and PW and receive different elaborations. The BW data are demodulated, filtered and elaborated (also according some parameters and filters set by the user) and then are sent directly to the BSC. For the CFM and PW, starting from the data filtered, are generated the I and Q signals. Also them receive different elaborations in case they are for CFM or for the PW Doppler and after all the elaborations are sent to the DCP. For the management of all the functions on board, there are is one DSP with its SDRAM. On it all the SW is stored at the start-up and every time it’s necessary. The DSP is in communication with some internal PLD and FPGA, which manage all the functions of the board and all the communication processes IN/OUT. There is a dedicated communication channel between DIP and IMC, where the DIP receives all the necessary data to manage the US information arriving from the ITRs. 4- 14

[Page 84] IMC (9501092000) The IMC (Input Master Controller) manages different processes inside the unit: -receives from the BLC all the necessary SW to program the front end (ICS, ITR and ICC) -it generates the sync and the timings necessary to acquire the US images -it controls the system gain and applies it during the various elaborations of the image -it checks the current necessary to generate the high voltage bang (high tension AT from SPR) and stops the unit in case of troubles -it check the temperature for the TEE probes -it manages the communication of the ICS and receives all the information about the probe connected. After the data are sent to the PC group in order to set the correct parameters of the probe and to show on the monitor the probe in the probe selection menu. -it manages the probe switch according the probe selected by the user At the start-up the board receives from the BLC all the SW necessary to set itself and the front end. Then the board start to check the presence of the boards ITR, ISC and ICC programs them. At the end the board informs the BLC that all has been performed. The internal DSP generates all the sync and all the focalization data necessary to process the various bangs. Also the gain to apply to the image is controlled by this board. The control of the current sent to the ITRs, to generate the bangs, is performed in order to control the power of the emission and to check for conditions of fault. In case of current out of range, the board can reduce it automatically or can disable the high voltage in case of short circuit. The IMC doesn’t check any other voltage sent out from the power supply group. The BLC makes this operation. For the TEE control there is a dedicated part of the board which controls the temperature and stops the system in case it reaches dangerous values. For the control of the probe selection the IMC receives from the ICS the information about the probe connected. When a probe had been selected it controls that the ICS enables the connector and that the bang are correctly sent from the ITR. 4- 15

[Page 85] DCP (9501094000) The DCP (Digital Color Processor) is the responsible about the creation of the CFM and Doppler trace (PW and CW). From the DIP the board receives the I and Q components (for CFM and PW). The mentioned data (digital) enter in a block of memory ready for the next elaborations. The data are filtered and elaborated also with the post processing settings. For the next elaborations of the CFM there are some DSPs, where the data are elaborated (vertical filtering, persistence, noise rejection….). After al the elaborations the data arrive to one DSP, which will send all to the BSC. For the PW the data from the memories arrive in one DSP which perform all the possible elaborations. In this DSP the audio signal is generated. The video data are sent to the another DSP and then out to the BSC. The audio is directly sent to the PVA inside the PC group for the next elaborations. The CW data from the ICC are first converted from analog to digital, then are elaborated as the PW. The same thing for the audio which is managed by the same DSP and then sent, as before, to the PVA. For all the communications between the board and the BLC there is a DSP. This component manages all the process at the start-up. It receives the programs from the BLC and answers all the requests. Also it manages all the internal processes according the settings selected. DEP (9501095000) The DEP (Digital Extended Processing) is a board dedicated for post processing elaborations on the BW image. In case the particular filtering is selected, from the DIP board the BW signal arrives to the DCP (it’s not received directly from the BSC). The DCP simply passes the signal to the DEP, without any elaboration. On the DEP the BW signal is elaborated by some DSPs according the filtering selected and then the result is sent to the BSC for the scan correlation. Also the DEP is programmed by the BLC. 4- 16

[Page 86] BSC (9501097000) The BSC (Back-end Scan Converter) performs all the operations of scan converter of the unit. From the DIP (or from the DEP) arrives the 2D and M; they are stored in the cine memory. The same is done for the CFM and Doppler data (both PW and CW). This is to compensate possible delay in the transmission of the data due to the elaborations. From the cine memory the data arrives in a memory where are mixed all the components, in order to create all the modalities (2D+CFM, M+CFM….). After all the elaborations the video data is sent to the BLC. For the ECG the data from the PSE arrives to the board where it’s mixed with the other US signals. In the board is also present the cine memory of the unit. The Cine data are stored in internal dynamic memories, ready to be visualized. BLC (9501099000) The BLC (Back Link Control) is the interface between the PC group and the rest of the unit. This board receives from the BSC the video data. They are stored in two video memories, one for the live condition and another for the storage of images and clips or for other processes as the 3D. The live image is sent to the PVA board to be visualized on the screen of the unit. At the start-up the BLC reads from one internal flash memory the HW composition of the system and checks that it’s correct. In case it’s necessary it programs again the flash. It programs directly all the boards of the back end (DIP, DCP, BSC, DEP) and the IMC (which will program the front end). After, it communicates with the PC group by the PLC (board inside the PC group) and downloads all the SW necessary to boot the unit, or to set again the unit after a modification of the system’s condition. Also controls all the communications processes of the unit and check the power supply group in order to see if it provides the right voltages outside. Inside the board there is a ROM device (ID button) where are stored all the passwords of the unit. In case of the replacement of the part it’s necessary to replace also this device and insert it in the new board. 4- 17

[Page 87] Power Supply Group 4 different boards compose the power supply group: Mains power, SPR, SPS and PSE. MAINS POWER (9501140000) The main input plug, the unit switch and the insulation transformer to supply the peripherals, compose this group. The line voltage is connected to the main switch of the unit. The line voltage is sent to the SPS (where it will be transformed in DC voltage) and to the insulation transformer, which will supply the peripherals of the unit (monitor, printers, VTR…). On this group there is the switch to select the line voltage between 220 or 115Vac. Both the lines to the SPS and to the peripherals are protected by fuses. SPS (9501100000) The SPS (Switch power supply) receives the live voltage from the Mains Power group and generates one DC voltage of 15 V. This 15Vdc is sent to the SPR and to the PSE; starting this voltage the SPR will create all the necessary DC voltages of the unit; the PSE all the necessary voltages for all the boards of the PC group, the keyboard and the display. On the SPS it’s generated also one variable DC voltage (in a range between 7 to 15 Vdc) which supplies the fans of the unit. This voltage increases its value with the internal temperature of the unit. This board generates the +5V (DC) for the stand-by. As soon as the mains switch is on, the SPS creates the +5 and sends it to the PSE. From this board the voltage is sent to the PC motherboard and to the keyboard group (on/off key). SPR MyLab Gold Platform (9501101000) The SPR (Switch Power Regulator) receives the 15Vdc from the SPS and generates all the necessary output voltages of the unit: +1.8Vdc, +3.3Vdc, +3.6Vdc, + 6Vdc, + 12Vdc, +5Vdc, AT (high tension for the bangs, DC voltage variable according the probe and the power of emission selected). On boards there are some control blocks, which set automatically the AT voltage according the probe selected. The board is controlled by the IMC (this part controls the current necessary for the AT by a check in the ITR) and the BLC, which check that all the 4- 18

[Page 88] voltages are in range and there aren’t short circuits or high values of current absorbed. 4- 19

[Page 89] SPR MyLab 70 (9501102000) The SPR (Switch Power Regulator) for the MyLab 70 works in the same way as the previous one. It receives the 15Vdc from the SPS and generates all the necessary output voltages of the unit: +1.8Vdc, +3.3Vdc, +3.6Vdc, + 6Vdc, + 12Vdc, +5Vdc, AT (high tension for the bangs, DC voltage variable according the probe and the power of emission selected). The only difference is that the board generates also one negative high tension for the bangs (-AT) necessary to drive the ITRs for MyLab 70. For this reason this board is not compatible with the MyLab Gold Platform units. On boards there are some control blocks, which set automatically the AT voltage according the probe selected. The board is controlled by the IMC (this part controls the current necessary for the AT by a check in the ITR) and the BLC, which check that all the voltages are in range and there aren’t short circuits or high values of current absorbed. PSE (9501109000) The PSE (PC Supply ECG) is responsible about the creation of the line voltages necessary of the boards inside the PC group, for the keyboard group and for the display group. This board is positioned inside the PC group (in the metallic chassis of the PC). Starting from the 15Vdc of the SPS the board generates + 5Vdc, +3.3Vdc, + 12Vdc necessary for all the boards inside the PC group. The board receives from the SPS the stand-by voltage for the boot and sends it to the PC motherboard and to the keyboard group (on/off key). As soon as the key is pushed the PSE start to supply the PC and the unit starts. The PSE supplies the keyboard group and the display group through the AKCP board. On the PSE there is also the ECG. On board there is a connector for the patient cable. The signal is amplified, filtered and converted from analog to digital. After, through one optoinsulator (to insulate the ECG part from the rest of the unit for safety reasons), the ECG signal is sent to the BSC for the next elaborations. 4- 20

Every command is sent to the KC (where are also positioned the TCG sliders) and where there is the controller of the keyboard group. On this board is also connected the alphanumeric keyboard. By two flat cables, the KC is connected to the display group. The keyboard group doesn’t send directly all the data to the PC, but it passes through the display group. KEYBOARD GROUP MyLab 70 (9102639500) Also the keyboard group for MyLab 70 is composed by the Keyboard Control board (KC code 9501106000), the alphanumeric keyboard, the trackball and the Keyboard Switch board (KS code 9501107000). The difference with the other model is in the layout of the keys. The system is able to recognize by itself the type of unit and to set the various keys according the unit. DISPLAY GROUP MyLab Gold Platform (9102706000) This group is composed by the Keyboard Display board (KD code 9501108000) and from a Display LCD.

On board there are two PS2 connectors for the alphanumeric keyboard and for the trackball (used as mouse). 4- 22

[Page 92] Both are wired to the PC motherboard. All the other commands are sent to the PC via USB (on this board there is a standard USB connector dedicated for this communication process). From the PSE arrives all the supply for the display and for the keyboard group. The Display group also drives the LCD display, which shows different menu according the system set-up and the user selection.

[Page 93] PC GROUP The PC Group is composed by the following part: PC motherboard, VGA board, Hard Disk, PVA, PLC, SoundBlaster, Video grabber, AKCP, VCP and PSE. The PSE has been described inside the power supply group but physically it’s located inside the PC box. PC MOTHERBOARD and PC PERIPHERALS Inside the unit there is a standard PC motherboard equipped with USB, LAN, PS2 connectors for keyboard and mouse, parallel, serial... The processor is a 3.2 GB (or superior) and the HDD is a serial ATA 80GB (or superior). From the display group there are two PS2 cables that connect the trackball (used as mouse) and the alphanumeric keyboard. The motherboard controls the external peripherals 5”1/4 (DVD Drive, CD..). Via USB arrives all the other commands from the keyboard; from the motherboard they are sent via PCI bus to the PLC and from this board to the rest of the unit. The VGA board send out the video sync. and the overlay to the PVA. In the HDD there is all the SW for the unit; at the start-up the PC reads it and via PCI send it to the PLC. The PVA receives the audio Doppler signal from DCP. The SoundBlaster receives the audio from the VTR and from the frontal microphone. Using one external cable jack/jack it sends all the audio signal to the PVA. The Video Grabber receives the Video signal from the VTR in order to show it on the screen. 4- 24

[Page 94] PVA (9501110000) The PVA (PC Video Adapter) receives the US video signal from BLC and the overlay from the VGA board. It mixes the two signals and sends out the result to the monitor or to the video peripherals (BW analog. Printer, VTR…). It receives from the VGA the video sync and sends it to the BLC. From the SoundBlaster it receives the audio signals from VTR and microphone. From DCP it receives the audio Doppler.

[Page 96] Chapter MyLab70 Probes This chapter provides a list of MyLab70 probes with their main characteristics. These probes have very different characteristics, so it is important to understand the differences to choose the best probe for the exam to be performed. The probe characteristics are related principally to the geometry and the frequency. Geometry Depending upon the probe’s geometry the characteristic of the ultrasound beam are changing and so a different type of image is made. In particular the probe geometry is related to the transducer geometry. The transducer is the part of the probe that transforms the electric signal in acoustic signal and vice versa. The types of transducer used with MyLab systems are: Linear, Convex, Phased Array and Doppler. Linear probes Linear probes (Linear Array) produce lines of view perpendicular to the transducer elements. They are indicated for applications with a constant field of view and they have a good definition in the whole field of view. Convex probes The convex probes (Convex Array) produce lines of view perpendicular to the transducer elements. They are indicated for applications that require a wide field of view in depth. Phased Array probes The Phased Array probes produce lines of view with angle variable with respect to the transducer elements. They are indicated for applications with a limited acoustic window (i.e. intercostal window) 5- 1

[Page 97] Doppler probes The Doppler probes are non-imaging probes that allow visualizing the Doppler signal. Thanks to the probes’ very small surface, they allow acquisition of the signal from very small acoustic windows. Linear/Convex probes The Linear/Convex probes are probes with two different transducers: one linear and one convex that allow for two different scan planes. Frequency In a probe the work frequency is related to the capability to penetrate in the body tissues. Low frequencies allow studying the deeper tissues, high frequencies allow to study the superficial tissues.

[Page 118] Chapter Troubleshooting The purpose of this chapter is to give some suggestion, in order to verify the most common problems that may happen on MyLab 70 and MyLab Gold Platform units (now indicated as MyLab ). It’s very important that every time there is a problem to send all information possible: s/n and software version of the unit defective, a picture of the defect with a description of it and, the following files that the unit creates: Echos_logxxx.log On these files are written the result of some checks that the unit makes as self-diagnostic, or report written when a fault happens. It’s important to underline that, not all the defect creates a report. For this reason all the information available are very important. In the same folder there is another file named platformsetup.log which summarize the result of every SW installation in the unit. This is useful in case of problems during the setup to understand which is the defective process, or if a mistake has been done. How to enter as administrator There are two ways to access to the system, one that gives the full controls on all the programs, with the possibility to explore the hard disk, add/remove programs without any protection and another similar but with less rights. The modalities are only for service purposes and they have to be used only by service technicians. The first modality (Administrator with full control) is by using one USB Service key code 8100264000: -it’s necessary to connect the key to one of the frontal USB plugs (with unit off), then turn on the system. With the USB service key connected, the system starts till Windows XP and it’s possible to enter in the various menu of the unit, add/remove programs/SW/files 8- 1

[Page 119] Figure 1 (USB Service key) Figure 2 (key inserted) The second modality (with less rights) is protected by password and to enter in this way (Administrator with less rights) it’s necessary to follow the next instructions: -it’s necessary to push the shift key as soon as the system starts; in the windows of login that will appear it’s necessary to write in the user field “Administrator” and the password is “laser”. Compared with the service key this way has less rights. How to simulate a probe -Enter as Administrator (with full control by using USB service key) and wait till Win XP ends the boot steps. -run MyLab program with a double click on the icon “Start” on the desktop -when the probe selection mask appear, with “CTRL” and “ESC” enable the taskbar and select the SW icon -will appear the following mask, select “Laboratory” and then “Probe simulation”, click on it 8- 2

[Page 120] -will appear the following mask, select the checkbox “Enable Simulation” and select a connector and a probe Replacement of a board To remove the board follows the instructions of the Chapter 3. After the insertion of a new board the system will recognize it and will program it without problems (unless compatibility problems with the SW release). 8- 3

[Page 124] How to download the error files Every time the system turns on, it creates a report in a dedicated file: The file is named Echos_logxxx and it’s stored in C:\Esatemp Inside the mentioned files there is a report about the status of the unit (SW release, SW processes started) and about the status of the various boards inside the unit. If one of them is in error a report will be created. Reading inside the files it’s possible to have the situation of the unit. The files are accessible starting the unit as administrator (both the ways) and it’s possible to download them by using one USB key or by the network. 8- 7

[Page 125] How to read the error files The first time the file is opened it’s necessary to select the application to read it. It’s possible to use the “WordPad” Sw. Inside the file are indicated different information about the unit (SW release, boot of the boards…) The following data is one example of a normal situaton: Wed Dec 14 16:01:53 2005 Log File Name : Echos_log021.log Max File Dimension...[default value]: 1024KB Log Files Number : 50 Enable Level Mask : 0x00000001 16:01:54.578 SW Version = --- Build = EV1187.O.000 16:01:54.578 Start: System Start Up 16:01:54.578 Start: Arguments: -ogwl 16:01:56.187 Start: End StartUp from Vtr.exe 16:01:56.234 Start: End StartUp from Gwl.exe 16:01:56.421 Start: End StartUp from Kbd.exe 16:01:56.484 Start: End StartUp from BioCom.exe 16:01:56.593 Start: End StartUp from Ecom.exe 16:01:57.859 Start: End StartUp from Executor.exe 16:01:59.218 Gws: IPC message size: 3440 16:02:00.453 Start: End StartUp from Gws.exe 16:02:00.453 Start: Send Go 0x4473 16:02:02.656 Hardware configuration I-Button: 2e-d4b9b15-01 Slot:[BLC] Firmware Code: Ver:1,Rev:0,Build:132 Pld Code: Ver:1,Rev:0,Build:e Slot:[BSC] Hardware Code: Model:6100,Comp:0,Rev:0, Dsp:TMS6713 Firmware Code: Ver:1,Rev:5a,Build:3e Hardware Code: Model:6100,Comp:0,Rev:0, Dsp:TMS6713 Firmware Code: Ver:1,Rev:0,Build:5ad Slot:[DCP] Hardware Code: Model:6100,Comp:0,Rev:0, Dsp:TMS6713 Firmware Code: Ver:0,Rev:1,Build:419 8- 8

[Page 128] The voice Hardware configuration checks if all the boards started correctly without problems. For example This message means that the SPR board started correctly (the error code is 0). Every time the error code is zero it means that the board was able to boot in the right way. In the following condition (for example): Error Code:[19] it means that the DEP board was not able to start correctly at the boot. In case a mistake appears during the run time (so when the unit is in live) the Echos_log file also add a little dump inside. In some boards directly controlled by the BLC, there is a location of memory where a report is written in case of error.

[Page 147] Chapter Protection against electrostatic discharges Opening and servicing MyLab70 and MyLab Gold Platform (now indicated all as MyLab ) it’s necessary to keep attention to the electrostatic sensible devices. In the unit are contained several boards and single components that can be damaged with electrostatic discharges. In the paragraph 10.1 are listed all the sensible parts. Handling them is necessary to follow all the precautions described in the following pages. Both on the field and in a laboratory the operator that touch the parts must be protected against the electrostatic discharges , using a dedicated kit on the field (an example is shown in the paragraph 10.4) or preparing an E.P.A. in the laboratory (electrostatic protected area). The tools used must be antistatic. All the operation on the field must be done with unit switched off , with the power cable disconnected. Where is necessary to check parts under voltage , the minimum value of resistance between the operator and ground must be 7.5 x10 Ω , in order to avoid risks for the operator. 10- 1

[Page 149] How to prepare an Electrostatic Protected Area (E.P .A.) Premise The purpose of an E.P.A. is to preserve from possible electrostatic damages all the electronic devices with threshold superior of 100V. Here below are listed some examples of E.S.D.S.(Electro-static devices sensible) : Device Minimum Threshold (V) MOSFET 100 EPROM 100 JFET 140 OP. AMP. 190 CMOS 250 It’s important to remind that the human body begins to be sensible at the electrostatic discharge when the value it’s over 2000 V. Everyone can damage an electronic device without notice. It’s possible to damage components even if are assembled on boards , for this reason is necessary to take care during all the phases like stoking , handling , reworking and installing boards. To have an E.P.A. where is possible to work with sensible devices in a safe way , it’s nowadays very important. 10- 3

[Page 150] CHARACTERISTICS OF THE E.P .A. To prepare an E.P.A. is possible without problem in every laboratory. It’s necessary to observe some little precautions : -the E.P.A. must be delimited with dedicated plates . -in the E.P.A. is forbidden :eating , drinking , smoking , changing clothes , using papers without antistatic shields, introducing material that generates electrostatic discharges (paper , plastic , nylon , adhesive tapes…) All the under mentioned things must be antistatic : -working surfaces (desks..) -floors -chairs -clothes (surplices , shoes , glovers …..) -tools -reworking instruments (soldering stations…) -envelopes where to stock boards (packaging…..) -containers for electronic devices -trolleys and envelopes for handling and carrying devices and boards Figure 1.: an E.P.A. (Image given by catalogue ”Ground Zero” for kindly license of OK International Spa). 10- 4

[Page 151] LEGENDA : 1) Containers for boards and devices 2) Testing instrument for bracelet shoes and overshoes 3) Envelopes and packaging antistatic 4) Testing point for shoes and overshoes 5) Trolley to carry boards and devices 6) Holder for documents 7) Warning plates 8) Ionizator 9) Ground connection 10) Ground cables to connect operator and floor 11) Chair 12) Surplices and bracelet 13) Shoes or overshoes 14) Antistatic carpet for floor 15) Service kit with tools 16) Antistatic cleaner Note :Also the soldering station must be connected to ground. The Antistatic carpet (point 14) is used where no antistatic floor is present. Is possible to put also an antistatic carpet on the table connected to the ground. The values of resistance of the various items contained in the E.P.A. are : Items Surface Resistivity Resistance to Ground Working surfaces and <1x10 9 Ohm/ € <1x10 9 Ohm floors Trolleys to move <1x10 9 ohm/ € <1x10 10 ohm (working plane) sensible components working plane <1x10 9 ohm (chassis) Surplices <1x10 12 ohm/ € Ground cables >9x10 5 Ohm <5x10 6 Ohm From hand with >9x10 5 Ohm bracelet to end of the <3.5x10 7 Ohm cable Shoes or overshoes >9x10 5 Ohm <3.5x10 7 Ohm Tools Not fixed <1x10 12 ohm Chairs Not fixed <1x10 9 ohm 10- 5

[Page 152] PRECAUTIONS FOR SERVICE OPERATION ON FIELD Also in service operation is necessary take care against electrostatic discharges. Particular service kits are reliable on market to protect the boards used. In Figure 2 is shown a service kit . Figure 2. LEGENDA : 1 :Conductive side of the mat 2 :Dissipative side of the mat 3 :Crocodile clip for each bonding to ground 4 :Bracelet for ground connection of the service operator 5 :Cable to connect mat to ground (by crocodile clip) 6 :Cable to connect mat to bracelet 10- 6

[Page 153] HOW TO USE THE KIT Connect the mat with cable 5 and crocodile 3 to a ground surface (e.g. chassis of the unit). Connect one side of the cable 6 to the bracelet and the other side to the mat. Wear the bracelet ; place the dissipative side of the mat on a safe surface then operate placing the boards in the conductive side. Don’t use the kit with parts under voltage. Where is necessary to check parts under voltage , the minimum value of resistance between the operator and ground must be 7.5 x105 Ω , in order to avoid risks for the operator. PRECAUTIONS TO SHIP AND STORE BOARDS In all the boards , as mentioned before , there are several E.S.D.S. components. For this reason particular precautions must be observed also storing and shipping boards: all the boards must be inserted directly in shielding envelopes, carefully closed with antistatic tape. No paper must be inserted in the envelopes with the boards. Don’t place in shielding envelopes : batteries , charged capacitors and others sources of power to avoid short circuit. Don’t use envelopes scratched or broken. Insert and remove the boards to and from the shielding envelopes only in E.P.A.

[Page 170] Chapter DICOM Connection DICOM (Digital Imaging and Communications in Medicine) is a standard (that is, a set of rules) for medical images and information exchange between different devices (computers, medical system, etc). DICOM’s basic features are listed below: • It encloses a communication protocol with detail specifications about image and information transfer • It defines an “open system” context allowing the connectivity among different manufacturers. • It’s based on standard computer network technologies and protocols (Ethernet, TCP/IP, removable media like CD-R and USB Pen drives). The standard is used and supported because: • DICOM is the only Medical Imaging and Communications Standard accepted worldwide. • DICOM is used for image transfer and archiving, search and retrieve from archiving systems and net printing in thousands network system installations. • DICOM is having an increasing integration with RIS/HIS (Radiology/Hospital Information System). • DICOM evolves in function of real needs. 12- 1

[Page 171] Brief description of a DICOM network A scheme of typical and complete structure of a network installation is shown in the following picture. The DICOM standard (Digital Imaging and Communications in Medicine) establishes, through the network (Intranet/Internet) or removable media exchange, a common language among: • modalities (US, MR, CT, CR, etc.), • medical printers (laser cameras), • PACS (Picture Archiving and Communication Systems: archive, viewing stations), • medical post-process workstations (for MPR, therapy planning, surgical navigation, etc.), • Information systems: HIS/RIS (Hospital/Radiology Information System). DICOM most used services are showed in next image: 12- 2

[Page 172] Network installation In order to connect a system to an existing Ethernet 10-Base T or 100-Base T network (i.e. in a hospital) cable is required. A UTP Cable (CAT-5) is needed. This cable also called “patch cable” has RJ45 connectors on both sides. Normally when connecting to the wall network plug, you should use a straight cable (see next figure). The network plug on MyLab is on the rear panel of the system. Once the hardware connection has been performed, the TCP/IP protocol of the system should be configured. 12- 3

[Page 173] Network configuration This procedure can be activated only if the Service key is inserted before switching on the unit. The Service key is required 1. Switch on the unit. 2. Press the Start key, highlight the Settings option and select Control Panel. 12- 4

[Page 174] 3. Double click the System icon; will appear the following window. 12- 5

[Page 175] 4. Open the tab Computer Name 12- 6

[Page 176] 5. Press the Change key in order to set the system working in a Workgroup or a Domain (anyway this information has to be provided from the network administrator). NOTE: do not change the Computer Name. 6. Press OK to confirm 7. Press OK to close the System Properties windows 12- 7

[Page 177] 8. In the Control Panel double click on the Network Connection icon; will appear the following window. 9. Right click on the Local Area Connection icon, will appear a menu. 12- 8

[Page 178] 10. Select properties; will appear the following window. 12- 9

[Page 179] 11. In order to configure the TCP/IP protocol, select TCP/IP Protocol option and press the Properties key, will appear the following window. 12. Select Use the following IP address and fill the fields IP address and Subnet mask. The other parameters are not obligatory except different needs specified from the network administrator. 12- 10

[Page 180] 13. The network administrator must provide all the network parameters. NOTE: normally you should never select the option “Obtain an IP address automatically”, because the DICOM devices must have static (that is not changing over the time) IP address to enable them to send data to other DICOM devices.. 12- 11

[Page 181] Performing MyLab70 Configuration for DICOM This section deals with the MyLab70 and MyLab Gold Platform (now indicated all as MyLab ) configuration for enabling the supported DICOM functions. The DICOM functions available with MyLab are indicated in our DICOM Conformance Statement. This procedure can be activated only if the Service key is inserted before switching on the unit. The Service key is required Before proceeding with the configuration it’s necessary that the DICOM option has been enabled. MyLab Icons Before all, please note that for accessing the various menus associated with the top icons you must freeze the image and press the “Pointer” button. Going with the pointer over the blue icons you can access a context-sensitive menu pressing the right button, while pressing the left button you get the action corresponding to the first item of the above menu. When a problem occurs, a red sign appears over the corresponding icon. 12- 12

[Page 182] Network Configuration Left-clicking the Hard Disk icon shows the “Properties” item of the corresponding menu. A message box will appear with the IP present Host Name, IP Address, free HD space and Application Entity Title of the MyLab. Right-clicking the Hard Disk icon and selecting “Network Configuration” (this item is present only with the Service dongle) shows the normal Windows XP network configuration panel: using it you can completely configure the network (IP address, DNS, etc.). Right-clicking the Hard Disk icon and selecting “IP Address Configuration” shows a panel in which you can configure the IP Address. Please note that selecting “GET AN IP ADDRESS AUTOMATICALLY” (that is, use the DHCP) could not work in DICOM environment, because the DICOM Archives and Printers normally need to know the IP Address of the MyLab to allow it to send/print images. When using this panel instead of the Windows XP network configuration, you cannot enable the DNS, so you will need to input the numeric IP Address of the DICOM Archives and Printers. 12- 13

[Page 183] DICOM Configuration - General Pressing the “MENU” button and selecting “DICOM CONFIGURATION” the DICOM configuration panel will pop up. In the GENERAL tab you can modify the local Application Entity Title of the MyLab (the default is “MYLAB”). Please note that the AE Titles are case sensitive. 12- 14

[Page 184] DICOM Configuration - Quality The images and clips are always sent and stored in DICOM using the lossy JPEG compression. In the “QUALITY” tab you will be able to select the quality level (HIGH=high quality, low compression, LOW=low quality, high compression). 12- 15

[Page 185] DICOM Configuration - Server In the “SERVER” tab you can input the configuration of the DICOM archive to send the images to. By pressing the “TEST CONNECTION” button you can send a Verification (C-ECHO) DICOM message to the server, to verify if at its IP Address and TCP port there is a listening DICOM application. Please note that normally this test does not check the AE Titles: the server will normally reply with a successful message even if the AE Titles are misspelled. The results of the test appear scrolling backward (last line first). 12- 16

[Page 186] DICOM Configuration - Report In the “REPORT” tab you can decide the way to export (to DICOM server or CD-R or USB) the measures and report. By selecting “BIOPACS” they will be put in a proprietary DICOM attribute, that the BioPACS can read. By selecting “OTHER SERVERS” they will be written in Secondary Capture images that everybody can read. 12- 17

[Page 187] DICOM Configuration - Print In the “PRINT” tab you will see the list of configured DICOM printers. You can add, edit or delete any item from the list. For every DICOM printer you can open the profile configuration panel by selecting the printer and pressing “VIEW PROFILES”. 12- 18

[Page 188] Adding a DICOM Printer Adding a new printer is like selecting a DICOM server. The only difference is that you must select a printer model. If the desired model does not appear in the list, it is normally possible to print using the “GenericPrinter” model. The description is a mnemonic description you decide to assign to the printer you are configuring. By pressing the “TEST CONNECTION” button you can send a Verification (C-ECHO) DICOM message to the printer, to verify if at its IP Address and TCP port there is a listening DICOM application. Please note that normally this test does not check the AE Titles: the printer will normally reply with a successful message even if the AE Titles are misspelled. The results of the test appear scrolling backward (last line first). 12- 19

[Page 189] Managing the Printer Profiles For every configured DICOM Printer you can prepare one or more Printer Profiles. When adding a new printer, the pre-defined printer profile is inserted in the list; you can modify it or add other profiles. 12- 20

[Page 190] Adding a Printer Profile You can configure the DICOM Printer Profiles according to the printing needs. For a given printer model, only the valid choices will be shown. The “DESCRIPTION” is a mnemonic name you can assign to the printer profile you are configuring. For the Layout, please note that only the “STANDARD\c,r” DICOM formats are allowed, where c is the number of columns and r the number of rows. If you select “Landscape” for the Film Orientation you will probably need a Layout in which the number of of the columns is greater than the number of the rows. 12- 21

[Page 191] Configuring the Print buttons Pressing the “MENU” button and selecting “PERIPHERALS” the peripheral configuration panel will pop up. In this panel you can select a peripheral to be assigned to each REC/PRINT button (two or three according to the model). By selecting DICOM PRINTER you will be able to chose the Model among the configured DICOM printers; after selecting the DICOM printer, you will be able to select the Layout among the configured printer profiles for that printer. 12- 22

[Page 192] Saving and sending images When closing the current exam (“START END” button), by checking the “ARCHIVE” selection, you can • archive it in proprietary format in the local database (“DB”); • save it in DICOM format on a CD-R or CD-RW (“CD”); • save it in DICOM format on a Pen Drive (“USB”); • send it to a DICOM server (“DICOM SERVER”). By selecting one or more exams from the “ARCHIVE REV.” panel, and pressing the “DICOM” smart key, you can • save them in DICOM format on a CD-R or CD-RW (“CD”); • save them on a Pen Drive (“USB”); • send them to a DICOM server (“DICOM SERVER”). In every case, you can decide to anonymize the images, removing the DICOM attributes that could identify the patient. Before saving the images on a CD-RW, you can erase it by selecting the “ERASE DEVICE” item in the menu that can be accessed by right-clicking the CD icon. In case of failure, a red sign will appear over the corresponding icon (CD, USB or Network); left-clicking over the icon will show the “OPERATION” panel with the list of the failed and successful operations. It is possible to retry the failed operations. To remove the red sign select the “RESET FAILURE FLAG” from the menu that appears left-clicking over the icon. Printing images You can print in DICOM every displayed image, by pressing the REC/PRINT buttons configured for a DICOM printer. Every time that you press the REC/PRINT button, the image is added to the current film, that will be actually printed when the number of images for that format have been added. The images printed from the real time and “EXAM REV.” environments are added to a different film from the images printed from the “ARCHIVE REV.” environment. When closing the current patient (“Start End”), the current films are printed. In case of failure, a red sign will appear over the corresponding icon; left- clicking over the icon will show the “OPERATION” panel with the list of the failed and successful operations. It is possible to retry the failed operations. To remove the red sign select the “RESET FAILURE FLAG” from the menu that appears left-clicking over the icon. From the above menu it is also possible to • force the printing of the current film (“PRINT NOW...”); • delete all the images already added to the current film (“RESET ADDED IMAGES”). 12- 23

[Page 193] Troubleshooting In case of DICOM problems, the first thing is to verify that the network is working correctly. To do this follow these steps: • reboot after inserting the Service dongle; • freeze the image and press POINTER; • press <Esc> and <Ctrl>: the normal Windows XP Start menu will pop up; • select “Run...” and input “cmd” • in the command window try to ping the gateway (if any) and the destination server and printers. Please note that Windows XP SP2, by default, enables the embedded firewall, so that, if you want to send data to a server installed in a PC with such Operating System, it is possible that from the PC you can ping the MyLab, but from the MyLab you cannot ping the PC. In this case you must disable or configure the firewall in the server’s PC. When you are sure you can ping the destination(s) from the MyLab, perform a verification, and then try to really send the data. If it does not work, write down the error(s) that appear in the OPERATIONS panel (select the item and press DETAILS), and collect the log files. Collecting the log files In case of DICOM problems, please collect the DICOM log files: • reboot after inserting the Service dongle; • freeze the image and press POINTER; • insert a USB pen drive; • select “EXPORT LOG FILES TO USB”; • after successfully exporting them, the DICOM log files are in the \MyLab_Log_Files\Dinamo folder of the pen drive. When sending the log files, please describe carefully the situation, the errors from the OPERATIONS panel, etc. 12- 24

[Page 194] Chapter Safety Test Every MyLab70 and MyLab Gold Platform (now indicated all as MyLab ) units comply with EN60601-1 (IEC 60601-1) standard. MyLab is Class I Type B and BF (Ultrasound probe) and CF (ECG) applied parts. It’s strongly recommended to perform Safety Tests every time new peripherals are powered through the plugs on the backside of the power supply, or you have to replace the following parts: • Power Supply Group (SPR, SPS, Main Power) • PSE board (ECG connector) Anyway we suggest to repeat the safety tests every two years. If the system is used in the Intensive Coronary Care, it’s suggested to repeat the safety tests once a year. Whenever the measured values exceed the reference ones (see the W A R N I N G following table) don’t use the unit and send it to ESAOTE The parameters to be tested are the following: • Impedance of Protective Earth Connection • Earth Leakage Current • Enclosure Leakage Current • Patient Leakage Current • Patient Auxiliary Current This chapter defines safety parameters and their range according to EN60601-1 standard and describes the safety tests to be carried out on the equipment. Note Performing the safety test, the operator has to keep attention also to follow all the precautions to avoid risks of electrical shocks. 13- 1

[Page 195] Definitions 1) Impedance of Protective Earth Connection The impedance between the Protective Earth (PE) terminal of the mains input connector and any accessible metal part. 2) Earth Leakage Current The current that flows from the mains terminals (P=Phase, N=Neutral) to the Protective Earth (PE) through the insulation. 3) Enclosure Leakage Current The current that flows between the enclosure and the Protective Earth (PE) terminal. 4) Patient Leakage Current The current that flows through the applied parts (i.e. ECG and US probe) towards the Protective Earth (PE). 5) Patient Auxiliary Current The current that flows between two different applied parts (i.e. between two ECG electrodes).
