1.2

Warnings WARNING The monitor cart power module contains live voltage even when the unit is switched of from the C-arm or monitor cart keyboard or the emergency switch is pushed in. Be sure to disconnect the unit from the mains supply when performing service work to the unit. WARNING The generator power supply in module 1 contains a large storage capacitor that filters the line voltage. The capacitor may contain high voltage even after the unit is disconnected from the mains supply.

WARNING Modules 1 (mobile stand power supply), 10 (monitor cart power supply) and 5 (X-ray generator) contain dangerous voltages. During operation the voltages exceed 250 VDC.

WARNING Parts of the C-arm may be contaminated infectiously. We strongly recommend to wear disposable vinyl gloves while doing service.

1.3

Required tests after service

The following tests have to be performed after every service: • Is the mechanics working properly? • Are all cables (P0, mains and swivel cable) in good condition? • Are the keyboards working properly? • Is the printout of the video printer okay (if printer is available)? • Is the system working fine? • Perform electrical safety check according to relevant national regulation of the country of installation Possible discrepancies must be recorded in the service report.

U333 Board versions

In the following; two different versions of the U333 board are described. In the board version "f" both the lift motor control and the lift motor power are connected to the same rectifier "GL1" In the board version "g" only the lift motor power is connected to the output of rectifier "GL1". The lift motor control is supplied via two additional diodes "D16" and "D18" connected to the input of the rectifier "GL1" by an additional cable. (→ Ch. 4.8, p. 4-9) This cable ia available as part No.29265. NOTE If an older board U333 "f" or below has to be replaced by a U333 "g" board, the cable between "GL1" input and U333g connector "X27" has to be installed also.

Circuit Description

4.9.1

Power-up circuit

Module 001 is supplied with mains voltage (230 VAC or 110 VAC) via terminal X1 (→ Fig. 4-10, p. 4-15). Transformer TR1 is constantly powered via mains fuses F1, F2, F3 and F4 (→ Fig. 4-10, p. 4-15) and back-up fuse F7. It thus keeps capacitor C1 constantly charged via secondary fuse F8 and diode D7. Module 001 is switched on by connecting the NETZEIN and EAGND signals (→ Fig. 4-10, p. 4-15), either via plug X17 (→ Fig. 4-11, p. 4-16) on the FST keyboard or via plug X11 (→ Fig. 4-11, p. 4-16) on the MW keyboard. Module 001 is switched off by connecting the NETZAUS and EAGND signals (→ Fig. 4-10, p. 4-15), either via plug X17 (→ Fig. 4-11, p. 4-16) on the FST keyboard or via plug X11 (→ Fig. 4-11, p. 4-16) on the MW keyboard. After switching on, relay K4 (→ Fig. 4-10, p. 4-15) picks up and latches with diode D1. The Power On LED (on the FST keyboard) is powered via resistor R5. Relay K1 (cut-off relay with 3 mm contact gap) picks up, and transformer TR1 (on the transformer panel) is switched to the power supply via fuse F5 and soft start resistor RL (on the transformer panel). Once electrolytic capacitor C2 has charged via the secondary winding (24 V, 3 A) (protected by fuse F3 on TR1) of transformer TR1 and rectifier GL3 (both on the transformer panel), and connected via plug X24 (→ Fig. 4-12, p. 4-17) and resistor R7, relay K2 short-circuits with the closing relay RL (contacts → Fig. 4-10, p. 4-15). Relay K3 (→ Fig. 4-12, p. 4-17) ensures that capacitors C and C2 are always discharged safely via resistors R6 and R3 during power off. The secondary winding (24 V, 5 A) (protected by fuse F2 on TR1) of transformer TR1 powers the lifting motor switching circuit via rectifier GL1 (both on the transformer panel). The secondary winding (24 V, 3 A) of transformer TR1 supplies module U326 (generator adaptation) in the 19" rack via rectifier GL3 (both on the transformer panel), plug X24 (→ Fig. 4-12, p. 4-17) and the central plug (on the transformer panel). The secondary winding (230 VAC) of transformer TR1 (on the transformer panel) supplies transformer TR2 (protected by fuse F1 on TR2 on the transformer panel). It also supplies plugs X3, X4 and X5 (→ Fig. 4-10, p. 4-15) via plug X7 (→ Fig. 4-10, p. 4-15) and fuse F6. The “Compact unit” section is connected to plug X5. The four 9 V secondary voltages (protected by fuses F5 – F8 on TR2) from transformer TR2 are supplied to module U334 (power unit for Module 2 via the central plug. The 24 V, 0.5 A secondary voltage (protected by fuse F9 on TR2) is used to rotate the image of the monitors (in the "Compact unit" section), while the 24 V, 4 A secondary voltage (protected by fuse F4 on TR2) powers modules BG1(18 V) and BG2 (coolant pump) via rectifier GL4 (on the transformer panel) and plug X12 (→ Fig. 4-13, p. 4-18). The 18 VDC voltage generated by module BG1 supplies Module 3, Module 4, the VacuDAP dose meter electronics and the signal horn (U80) via plug X19 and the central plug. The 18 VDC voltage also supplies the mobile stand keyboard via plug X17 (→ Fig. 4-11, p. 4-16).

The screening between the primary winding and the secondary windings is connected to PE potential on all three transformers. (TR1 and TR2 on the transformer panel and TR1 on U333). During power off, the excitation voltage is disconnected from relay K4 (→ Fig. 4-10, p. 4-15). Relay K4 then drops out, followed by cut-off relay K1 (→ Fig. 4-10, p. 4-15). Diodes D2 and D3 are used to isolate the on/off circuits in the mobile C-arm stand and monitor cart.

4.9.2

Output switching circuit

Secondary winding 1 of transformer TR1 (on the transformer panel) supplies the operating voltage for generating high voltage for the generator. The three tapping points 90 V/120 V or 136 V/ 195 V are linked to plug X9 (→ Fig. 4-12, p. 4-17). The /POWER1 signal at plug X11 (→ Fig. 4-11, p. 4-16) activates relay K5 (→ Fig. 4-12, p. 4-17), while the /POWER2 signal at plug X11 (→ Fig. 4-11, p. 4-16) activates relay K6 (→ Fig. 4-12, p. 4-17). The selected voltage is supplied to capacitor C (on the transformer panel) via rectifier GL2 (on the transformer panel) and plug X14 (→ Fig. 4-12, p. 4-17). Relay K7 is activated via transistor T1 when the /CANSTÖR signal at plug X10 and X13 (→ Fig. 4-12, p. 4-17) is “HIGH” (default). The capacitor voltage is then connected through to the generator via plug X15 and X16. The CAN signals are routed from the central plug (on the transformer panel), via plug X10 and X13 (→ Fig. 4-12, p. 4-17) to the FST keyboard. Resistor R6 is used to quickly discharge capacitor C (on the transformer panel) when the device is switched off.

4.9.3

Lifting motor control circuit

This part of the circuit is supplied by secondary winding 2 of transformer TR1 (on the transformer panel). This voltage is routed from X23 (→ Fig. 4-11, p. 4-16) via GL1 (on the transformer panel). Resistors R01 and R02 (on the transformer panel) are also connected to this plug, and serve to limit the lifting motor operating and braking currents. The lifting motor is connected to plugs X21 and X22 (→ Fig. 4-11, p. 4-16) and is short-circuited via the relay contacts of K8 and K9 when set to Off. The voltage regulator IC5 is supplied via diode D16, resistor R28 and Zener diode D17. It generates the supply voltage for the electronic circuit. The “Lifting motor up” and “Lifting motor down” keys on the FST keyboard are linked to PCB U333 via plug X17. The limit switches connected to plug X18 limit the traveling range of the lifting motor. When they reach their end position, they open the contact, and the lifting motor cannot travel any further in this direction. The Schmitt triggers IC1D and IC1E are linked to AND gates IC2B and IC2C and prevent the motor running if the “Lifting motor up” and “Lifting motor down” keys are pressed at the same time.

4 Power Supply

Starting the lifting motor: The travel command (jump to “HIGH”) is routed to resistor R20 and R21 and to AND gate IC2B or IC2C via resistor R19 or R22. Capacitors C12 and C13 debounce the control keys. When the travel command is reversed by IC3C (or IC3F), capacitor C11 quickly discharges via diode D14 and resistor R24 (or C3 via D13 and R8). The Schmitt trigger IC3A (or IC1B) activates transistor T3 (or T2), and relay K9 (or K8) picks up, thus selecting the direction of travel. The travel command changes to a jump to “LOW” at the output from AND gate IC2A. Capacitor C14 is slowly discharged via resistor R17. The Schmitt trigger IC3F then activates transistor T4 and relay K10 picks up. The lifting motor is powered with voltage and moves down. Stopping the lifting motor: The stop command (issued by releasing the “Lifting motor up” or “Lifting motor down” key) discharges capacitor C12 or C13. Capacitor C14 is also quickly discharged via diode D11 and resistor R18. Relay K10 thus drops out immediately and disconnects the lifting motor from the supply voltage. Capacitor C11 or C3, on the other hand, is slowly charged via resistor R23 or R9. Relay K8 or K9 drops out after a delay, and the lifting motor is short-circuited once more. Monoflop IC4A responds to the falling edge at pin 1. The monoflop issues the “LOW” signal for approximately 200 ms (set using resistor R26 and capacitor C17). This prevents the lifting motor from starting up again after a stop command for the duration of the set time constant.

U325 functional description

The slide-in board U325 is the central control unit of the C-arm. All machine data are stored on this board. Machine data include information about: − options − start up configuration − diaphragm settings in case of standard collimator − kV - mA characteristics − hand and foot switch configuration. The board receives data via the CAN bus from module 3, calculates the kV and mA nominal values and forwards them as data words via the internal LUCY bus to the U326 board. Also the information for diaphragm setting and laser switching are transmitted that way. The hand and foot switches are monitored for short circuits. The real time clock counts up the radiation time and is used to create an error log. The safety logic prevents from unintended radiation. There is a detailed description in → Ch. 5.7, p. 5-16 “Hardware Radiation Logic” The monitor cart detection controls the CAN bus termination logic on board U334. The power switching controls the relays K5 and K6 on the board U333.

5.4.4

U326 functional description

The slide-in board U326 is the control board for the generator. Here the data words coming from the U325 board are converted to analog values and discrete switching signals: − 12 bit words are converted to mA and kV analog control values − Slot and Iris collimator controls are decoded and sent to the collimators via drivers. (only used for standard collimator) − Laser switch command is decoded and sent to the generator − radiography mode command is decoded and sent to the generator. The mA nominal value is compared to the actual value measured in the generator. The difference controls a switching regulator, which generates the filament voltage from 24 V input voltage. A temperature switching signal (0.5 mA) is received from the generator. This signal is encoded on the U326 board and sent to the U325 board in order to control the system depending on the generator temperature. The fault line coming from the generator is received. This signal is monitored by the fault LED on the U326 board and is connected to the CAN fault line by an optocoupler. Also 15 V and ±10 V for the board supply are generated. The voltages are monitored on the front of the board.

Exchange of boards

5.6.1

Exchange of U325

After exchange the U325 board has to be programmed. There are two steps of programming. First, if the warning E35 appears, the software versions of the board and the rest of the system have to be adapted. Then the machine data have to be restored. It is recommended to save the machine data before you remove the original board, if communication to the board is possible. If the data cannot be read out and no archived data are available, use default data and set options manually. If there is a warning E32 after exchange, the RAM test pattern must be set. If there is a warning E34 after exchange, the Clock must be set. → Ch. 18.1.4.1, p. 18-6 and → Ch. 18, p. 18-1 Software Tools U325 to be changed

5.6.2

Exchange of U326

After exchange the U326 board has to be adjusted according to the following instructions:

1 General: C-arm has to run properly before adjustments can be made. The potentiometers and their labels at the front panel (U326): − P5 mA offset − P4 pre-heating − P3 mA DAC offset − P2 exposure − P1 kV offset Necessary test equipment: Test cable to generator (to check the actual generator values) Test cable to the front connector of U326 (for the signal names refer to the U326 schematic) PC with USBCAN or PARCAN test set.

2 Adjust filament voltage without exposure • Set fluoroscopy mode, connect test cable to the front connector of U326 Connect voltage meter to: + with UH - with GND Adjust potentiometer P4 to 12.0 V (P4 = pre-heating)

3 Adjust mA offset with exposure • Set fluoroscopy mode, set kV manual and 40 kV Connect ampere meter instead of the mA bridge in the generator. Adjust potentiometer P5 to 0.2 mA (P5 = mA Offset) • Measure the voltage UH with exposure and keep the voltage value in mind. Adjust pre-heating to memorized value with potentiometer P4 without exposure.

4 Adjust kV with exposure • Set fluoroscopy program extremities, set kV manual and 80 kV Connect voltage meter to + with kV measuring point “f” – with generator ground Adjust potentiometer P1 to 8.0 V (1 V equals 10 kV) Check voltages at 40, 60, 100, 110 kV

5 Adjust mA with exposure, top value Set spine / pelvis fluoroscopy program (program 2), set kV manual and 65 kV (mA display has to indicate 6.0 mA) Connect ampere-meter instead of the mA bridge in the generator. Adjust potentiometer P3 to 5.95 mA

6 Adjust mA with exposure, bottom value • Set spine / pelvis fluoroscopy program (program 2), set kV manual and 40 kV Connect ampere-meter instead of the mA bridge in the generator. Adjust potentiometer P5 to 0.2 mA !! Repeat the two steps above, because these steps interact with each other !!

7 Current rise time in active radiography mode • Set radiography mode, set radiography exposure time to 0.1sec • NOTE: the exposure starts approximately 1 sec. after pressing the hand switch (pre-heating time) • Connect the mAs meter instead of the mA bridge in the generator. Adjust potentiometer P2 to 2.0 mAs

8 Adjust radiography current with exposure • Set radiography mode, 80 kV and 4 sec. radiography time. • NOTE: the exposure starts approximately 1 sec. after pressing the hand switch (pre-heating time) Connect ampere meter instead of the mA bridge in the generator. Adjust the current to 20.0 mA which means you have to enter the appropriate number in the field “D/A Converter Radiography” of the Exposcop Studio software. The default value is 20 (20 mA). Allowed value range is from 15 (15 mA) to 28 (28 mA). ! If the value is out of range there is a hardware failure ! For adjustment use the “DAC value” entry of the above menu. Allowed value range here is from 614 to 1147.

9 Adjust radiography mAs with exposure • Set radiography mode, 80 kV and radiography exposure time to 0.5 s • Do not forget: the exposure starts approximately 1 s after pressing the hand switch Connect mAs meter instead of the mA bridge in the generator. Adjust potentiometer P2 to 10.0 mAs.

10 Check pulse fluoroscopy • mA values identical to fluoroscopy.

11 Check snapshot mA • This value has to be set to 8 mA. This is done using the Exposcop Studio software. • Section Generator, D/A converter snapshot.

6.3.2

U180 functional description

There is a U300 processor board (LUCY) on the U180 board. Thus module 3 is part of the CAN bus. On the U300 board the anatomical program data are stored. Anatomical program data contain values for: − dose and video adjustment − diameter of the gauging circle − regulation mode. Values are stored independently for every anatomical mode and magnifier size. The U180 transmits values for Iris and AGC to the CCD camera. The iris position is fed back to the analog inputs by a potentiometer. At the analog multiplexer there are also values gained from the video signal in order to do dose and video regulation. The average or peak value is compared to an internal value. The difference is transmitted by the CAN bus to the module 2 to regulate the necessary dose value. The black and white values are compared to values stored in the organ table. The difference controls the black clamping and white clipping (video adjustment, → Ch. 19.1.2, p. 19-3).

U321 functional description

There is a digital circle generator on the U321 board. This generates the gauging and blanking circles. Within those areas, the video signal is measured and the result is sent to the LUCY of the U180. The signal stages “curve” and “white level regulator” are controlled by the LUCY of the U180 board. In the signal mixer the video signal is overlaid by the blanking circle. Sync signals are separated from the video signal in order to synchronize the circle generator and additional hardware for Compact units. (Image memory, 100 Hz converter)

7 Image Intensifier

7.2.1

Functional description

The image intensifier can be divided into three electrical units: − The CCD sensor forms together with the iris collimator and the lens the CCD camera. − The image intensifier tube. − The intensifier power supply consisting of the boards U316, U317 and U318. The latter supplies the intensifier tube and the CCD camera. The U316 is supplied with 18 V. From this 18 V the supply voltages for the CCD camera, the grid voltages and the anode voltage are generated. The voltages for G2 (focus) and G3 (image size) are separately adjustable for every fluoroscopy format. The grid voltages are switched by signals coming from module 3. The anode voltage is factory pre-adjusted to 30 kV and must not be changed. (Tube might be damaged) The voltage for G1 is given by the tube manufacturer according to the tube type. It makes up the edge focusing.

7 Image Intensifier

7.6.1

General description

The CCD sensor is a solid-state imaging device that produces a black and white image. Light entering wells in the sensor are converted to electrons, which are read out from the sensor, amplified and converted to a digital video signal. The video signal is transmitted via an analog video coax cable to the image processing system.

7.6.2

Setting the CCD camera distance

The camera distance is set by using different mounting rings. The camera will be shipped without a mounting ring. For installing the camera, the ring has to be taken from the camera that has been installed before. II Tube

Installing the CCD camera

Fig. 7-16

Mounting of the CCD camera

The camera is put onto the output window and is fixed by the mounting ring using 3 allen screws. If the camera has not been removed from the mounting ring, the assembly is done in reversed order. Please check optical focus afterwards. If the camera has to be changed, it has to be mounted and centered to the ring that has been assembled to the unit. After installing, the optical focus has to be set. NOTE For the 12" tube, a 7/64" Allen key is required. For all other tubes, a 3 mm Allen key is required.

NOTE The connections have to face towards the C profile, in order to provide correct image orientation.

CAUTION Make sure that you have selected the correct supply voltage at the i.i. power supply, U316, J1 (→ Ch. , p. 7-8).

Adjustment of the optical focus

• Switch off the unit. • To focus the camera lens, the camera cover has to be removed. • For that, remove the intensifier power supply (only the screws, not the connectors) and loosen the grub screws at the camera housing (→ Fig. 7-17, p. 7-14). • Switch on. • Center a line pair phantom to the input window. The line pairs should be 45° to the monitor line structure and 90° to the scattered radiation grid • Loosen the locking screw. Set to magnifier 2 format and adjust to maximum resolution. Use a 2 mm nib (Part No. 91118) for focus adjustment. • Switch to full field size and check edge focus. Tighten locking screw hand screwed. • Put on camera cover and lock it by the grub screws. • Assemble i.i. supply, led weight and i.i. cover (incl. earth cable)

WARNING Focus adjustment is done while screening. Take care for radiation protection!

Checklist for the Generator

The following steps show the signals required for the generator to work properly: Measurements are made on the U185 Filter frame. 1. U1 (final stage supply) must be in the range of approx. 130 to 280 VDC depending on the operating mode. (Generator power in W). This voltage has to be present in standby also. Check the voltages at each of the three stages. (see table below) Screen once before measuring. If E26 is present, the voltage is switched off by module1 for safety reasons. The test points are: plus minus

X11 Pin 2 X11 Pin 4

2. U2 (supply voltage) must be 15 VDC. The test points are: plus minus

X12 Pin 2 X12 Pin 1

3. UH (filament voltage) must be in a range of approx. 9.5 to 11 VDC in standby and approx. 9.5 to 18 VDC while screening depending on selected mA value. If the voltage gets below 7.5 VDC, the generator pulls the fault line (E26) If the voltage gets above 22 VDC for a certain time, the filament regulator on the U326 switches off and radiation will be interrupted. The test points are: plus minus

X11 Pin 3 X12 Pin 1

4. kV reference voltage must be in the range of 8.1 to 12 VDC depending on the selected kV value. Voltage has to be also present during standby. 8.1 VDC equals to 40 kV and 12 VDC equals to 110 kV; 55 mV is 1 kV step. The test points are: plus minus

BG2 Pin 4 (kV ref.) BG2 Pin 2 (kV ground)

5. Radiation command input is active if BG2 Pin 8 is about 0 V; inactive level is 15 V. The test points are: plus minus

BG2 Pin 8 (radiation) X12 Pin 1

Changing the Collimator

9.4.1

Part exchange

• Remove connectors X7, X9, X10, X11, X12, X13. • Remove the 4 mounting screws. With power switched off, the collimator can be rotated in order to access the screws. • Fit the DAP-meter to the new collimator • Mount the new collimator with the 4 screws. Take care about the pre-collimator. Do not tighten the screws, because centering is necessary. • Connect X7, X9, X10, X11, X12, X13. Power up the unit.

9.4.2

Mechanical centering

• Press briefly both buttons of each function of the collimator (iris, slot, rotation) to get the starting position. • Close the iris collimator to a diameter of approx. 10 cm. • Screen in order to get an image of the collimator. • Press briefly one of the collimator buttons to display the preview. • Adjust the center of the collimator. • Repeat the two steps above until collimator is centered to preview. • If the image of the collimator is in the center and you can see a hexagon, the adjustment was successful. • Tighten the collimator mounting screws. • Press the both buttons of each collimator control (iris, slot, rotation) to get the starting position.

General Description

The monitor cart module 10 power supply is the main power module for the Ziehm Vista C-arm and provides − power isolation from mains input − internal power distribution of 230 VAC to the monitor cart and through the XP0 for the mobile stand − inrush current limiter − on/off circuitry − emergency stop and key switch lock for power

14.3

Main Components of Power Module 10

Isolation transformer TR1 provides: − isolation from the mains line power supply − input voltage taps for matching the input voltage to maintain 230 VAC output − the main supply voltage for the complete C-arm U357 power distribution board provides: − power on/off control − distribution of power − U357 allows an easy method for matching the input line voltage to the facility power − matching TR1 input to mains line voltage − the ability to set the correct voltage is accomplished by following the power selection table in the diagram below − X12 to X21 terminals for matching input line to TR1 − output 230 VAC for system

Ziehm Vista / Ziehm 8000 P_26363/CD_28115 - 09/03/2010

14 Power Supply

Matching the line input to TR1: Matching the line input to facility is accomplished by performing a simple measurement of the wall outlet connector with a digital volt meter. Monitor the voltage for a period of time long enough to detect any unusual dips in the mains line (10 to 20 minutes). NOTE Those facilities demonstrating large fluctuations in the mains line voltage may require a more detailed measurement test. Placing a lines voltage monitor and monitor the line voltage for 12 to 24 hours. This is an important issue and should not be overlooked. Once the line voltage is determined to be stable and within the range of the selection table the service technician must follow the tap setting and jumper placement as required in the Voltage Selection table for the U357 board.

230 VAC power distribution U357: − the output of the TR1 transformer (X10 and X11) supplies 230 VAC to the U357 board − distributes 230 VAC to auxiliary equipment by means of the terminal connectors X24 to X30 − supplies power to devices such as video monitors, printers, image system, etc. − distributes 230 VAC power to the mobile stand by means of the power connector terminals X22 and X23

Recursive filter The recursive filter adds a certain number of images (which are determined by the preset level) during fluoroscopy. Each newly-acquired image is superimposed by the result of the previous addition with a certain weighting factor. The higher the number of images, the greater the noise suppression, but also the greater motion blurring. The values can be set independently for normal view, magnification 1 and magnification 2. The values are displayed in the lower left corner of the live screen in the following form: N=0, N=1, N=2, N=3. The preset values can be adjusted during operation with the F2 and F3 keys on the C-arm stand control panel. Stack filter The stack filter generates and adds the preset number of images after radiation has been terminated. The higher the preset number of images, the greater the noise suppression, but also the greater motion blurring if the patient moves during image generation.

Edge filter The edge filter is used for setting a greater or lesser degree of enhancement (sharpening) of edges within the image. 4 levels of edge enhancement are available: Level

Meaning

0

No edge enhancement (original fluoroscopic image)

1

Slight edge enhancement

2

Medium edge enhancement

3

Strong edge enhancement

Increasing the level of edge enhancement will also cause any noise in the image to become more apparent, though. Windowing step This value determines which windowing step is automatically set by the system for the corresponding anatomical program after power-up, provided that the step windowing mode has been activated (→ Ch. 15.11.3, p. 15-13). You can adjust these default settings later during operation using the contrast keys on the C-arm stand. Continuous pulse This setting defines how many images are used for the stack filter in continuous pulse fluoroscopy mode (overriding the value specified under Stack filter). Snapshot This setting defines how many images are used for the stack filter in snapshot mode (overriding the value specified under Stack filter). NOTE Default values are listed in the adjustment chapter.→ Ch. 19.2.3.3, p. 19-15

DICOM Overview

DICOM means Digital Imaging and Communications in Medicine. This worldwide standard was developed by ACR and NEMA for the exchange of information between digital imaging computer systems in medical environments. The Ziehm C-arm can be supplied with 5 DICOM options: 1 With the DICOM Storage option you can send x-ray documentation to a DICOM computer network. With DICOM Storage Commitment you can get a confirmation from the archive that an image is saved. 2 With the DICOM Media Storage option you can save x-ray documentation to a 650 MB formatted MO disk or DVD/CD. 3 The DICOM Query/Retrieve option is used to query patient, study, series and image data from a computer network. 4 The DICOM Worklist option is used to query a worklist job for today from a computer network. MPPS can be used to send worklist jobs into the status “in progress” and finally “completed”. 5 The DICOM Basic Grayscale Print option is used to print x-ray images to a computer network. The basic document of the DICOM application is the “Conformance Statement”, which is obligation for every “DICOM participant”. With this document you can decide whether the communication between Ziehm C-arm (SCU = Service Class User) and server (SCP = Service Class Provider) will be successful. The DICOM transmission needs the network parameters described in the following section:

Exposcop Studio

This program is a tool with which you can perform various service procedures on the mobile X-ray systems of the Ziehm 7000, 8000, Compact and Vista series. This requires, however, that you have acquired the necessary skill and knowledge by attending a training at Ziehm Imaging. If this is not the case, you should not try to change the settings of your Ziehm C-arm with this program, but instead request a trained service technician from Ziehm Imaging.

18.1.1

Connection between notebook and C-arm

Communication between notebook and C-arm is established via a CAN interface. There are two possibilities to connect a notebook to the C-arm: • Via a USB-CAN adapter • Via a PARCAN adapter (not available as a new part anymore) The connection must be configured in the Exposcop Studio “Interface Selection” dialog box.

18.1.1.1

Location of the service connectors

The CAN adapter is connected to the hand switch socket.

18.1.2

Starting Exposcop Studio

In order to start the Exposcop Studio, you will find the Exposcop Studio under Start menu > Programs > Ziehm Imaging > Exposcop Studio. It is recommended to create a shortcut on the desktop. When you start the Exposcop Studio software, the GUI (Graphical User Interface) possibly may not start. If you get a window “Connecting the Exposcop”, followed by a message box “Interface”, the USB-CAN or PARCAN adapter cannot be found.

Fig. 18-13

Update procedure

After a software update the machine parameters have to be reloaded into the Ziehm C-arm. Therefore it is required to specify the desired machine data files before the update. These files will be administered according to the following rules: − When you press the “Select data file” button, you specify a set of machine data files (.mad and .org) that you want to use. A temporary copy will be made of these files. − When you press the “Read data” button, the machine data will be read out of the Ziehm Carm. The directory where they will be stored is specified under the “Settings\Machine data directory ...” menu item. The file names will be created from the serial number of the Ziehm C-arm and the extensions .mad (for machine data) and .org (for organ data). Once this data is known in the Studio Software, the buttons “Program” and “Write data” are enabled. With the “Program” button you start the programming procedure. This will perform all the necessary steps for the software update: − The machine data are converted to fit the desired software version. This means that for new machine data default values will be given and the current machine data will be transformed in the format of the new version. Should this conversion be not possible, the programming will be cancelled in this place before data in the Ziehm C-arm will be changed. − The software will be written to the EEPROM memories of the Ziehm C-arm modules. Only those modules that are checked in the list of modules on the right, will be programmed. However you should always program all modules to avoid compatibility problems. − The Ziehm C-arm will be reset, so that the modules are synchronized. Because the machine data are not yet loaded by this time, various error messages might be displayed which can be ignored. − The machine data that had been converted in the first step are transmitted back to the Ziehm C-arm. Depending on the old and new software version another reset of the Ziehm C-arm might be necessary. Eventually perform this reset by switching the device off and on. Please note that the programming procedure can take more than 30 minutes. Cancelling the programming usually leaves the Ziehm C-arm not functional so that you have to repeat the programming before you can put it into operation.

Offline mode

In offline mode you create floppy disks for updating the Ziehm C-arm or for assigning the foot switches without a direct CAN bus connection to the device. Because the Studio Software cannot read the data from the device, you first need to provide some information about the Ziehm C-arm for which you create the floppy disks.

Fig. 18-22

Offline mode serial number dialog box

Enter the type of the Ziehm C-arm (Ziehm 7000 or Ziehm 8000 and Ziehm Vista) and the serial number of the mobile stand. In the following dialog box you can choose if you want to create floppy disks for a software update or for changing the foot switch assignment. (Floppy disks for changing the foot switch assignment can be created only for the Ziehm 8000 and Ziehm Vista.)

18.1.18.1 Floppy disks for software update NOTE Programming only will work on a PC with Microsoft® Windows® 98 or older using the PARCAN adapter. To prepare floppy disks for the software update, select the desired software version. If there is any data in your machine data directory for this machine, you can start immediately with the creation of the floppy disks, otherwise the “Create” button is disabled (dimmed) and you must select the data files first. During the creation the software will generate two subdirectories called “Old” and “New” in your directory for the disk images. “New” contains the files for the update. Copy these files (e.g. using the Windows® Explorer) to a floppy disk. To perform the update, connect a PC via a PARCAN adapter to the Ziehm C-arm, insert this floppy disk into the PC and start the update procedure with the command a:\prog. During the update the machine data which have been fitted to the software version will be transmitted, too. In the “Old” subdirectory, you will find a disk image to undo the update process. Execute the undo exactly like the update, i.e. copy the files on to a floppy disk and start prog.bat from this floppy disk on the PC which is connected to the Ziehm C-arm via PARCAN.

18.1.18.2 Options - switch assignment For the Ziehm 8000 and Ziehm Vista you can create a floppy disk set to change the hand and foot switch assignment. Since these floppy disks are used with the HEDIS, you have to enter its serial number. The setting of the assignments done the same way as in the online mode. During the creation a subdirectory called “Switch” will be generated in the directory for disk images. Copy the files from this directory to a floppy disk (e.g. using the Windows® Explorer). You can transfer the switch assignment into the Ziehm C-arm via the floppy disk drive of the monitor cart.

Problem correction

With the selected interface no connection to the Ziehm C-arm can be established. Possible causes of this problem are: The Ziehm C-arm is not switched on.

Switch on the Ziehm C-arm and wait until the kV and mA values are displayed on the keyboard of the mobile stand. Then press “Repeat”.

The cables to the Ziehm C-arm are defect, not plugged in or loose.

Check all the cable connections. Eventually replace the cables with new ones. Then press “Repeat”.

An external PARCAN-Adapter has no power supply.

Check the power LED on the PARCAN.

PPARCAN Adapter requires a reset

Please note that the external PARCAN-Adapter has to be eventually reset after a failed connection attempt. To do this unplug the PARCAN power connection, wait for a few seconds and plug it in again. Then press “Repeat”.

CAUTION Radiation might be released during reset of the PARCAN adapter!

If the Studio Software cannot connect the Ziehm C-arm even though it succeeded to initialize the interface, several causes are possible. Possible causes of this problem are: The cables to the Ziehm C-arm are defect, not plugged in or loose.

Check all the cable connections. Eventually replace the cables with new ones. Then press “Repeat”.

The Ziehm C-arm has not finished its startup.

Wait until the kV and mA values are displayed on the keyboard of the mobile stand and try again.

The module “Main Controller” in the Ziehm C-arm does not respond.

The module 2 (U325) has no system program. Select the option “Module Programming” in the dialog box that is being displayed, choose U325 and the required software version. After successful programming you have to turn the Ziehm C-arm off and on again and load the machine data anew.

The Ziehm C-arms breaks the programming procedure after a short time with the message “Programming failed!”.

The reason is in most cases the configuration of the parallel port. This interfaces operates with modern printers in ECP or EPP mode. This does not work with a PARCAN adapter, however. Please set the parallel port back to “Standard Mode” if you get this message. This is done after power-up of your PC in CMOS setup. For details on that refer to the manual from your PC manufacturer.

19 Adjustment Instructions 19.1

Dose & Video Adjustment

Dose adjustment has to be performed prior to the video adjustment. The adjustment of dose is performed with 25 mm Al + 1.5 copper put onto the generator. The dose is measured in front of the image intensifier grid. The dose values have to be taken from the dose table. You can adjust dose with the following parameters:

19.1.1

Dose Adjustment

19.1.1.1

Dose adjustment parameters

− Iris collimator − This value influences the actual Iris CCD collimator. A smaller value leads to a higher dose and vice versa. − AGC − This value influences the internal gain of the CCD camera −

Increasing the value will increase the dose.

19.1.1.2

Dose adjustment procedure

• Set to Full Dose • Set iris collimator and “AGC full dose” to values given in the Organ Table. • Adjust to full dose value by setting the iris collimator in the specified range • If dose level is not adjustable then change “AGC full Dose” value. • Set to Half dose • Adjust to half dose value by changing “AGC half dose” value

19 Adjustment Instructions

19.1.1.3

Special cases for dose adjustment

− Half Dose: Dose has to be adjusted at full dose first. By activating half dose, the iris collimator value is blocked. Half dose value adjustment is only done by changing “AGC half dose” value − Snapshot: Snapshot is a modifier to each application program and is adjusted via “Iris collimator snapshot”. Measure the accumulated dose for one shot. Do not measure the first shot, make sure that regulation has found its target before. Dose has to be below 2uG. − DSA / MSA / RSA: Assign the DSA function to the thorax key to do the adjustments without the DSA functionality of the Image Memory. → Ch. 18.1.6, p. 18-11 ff. After Adjustment assign the prior function to the thorax key again.
