2 - 2 Functional description

Biopsy controller 2

The biopsy controller has three main funct ions:

• Biopsy unit control

• Switching of RS-232 from MAMMOMAT to either MAMMOMAT printer/service PC or

workstation

• CCD camera power supply

Biopsy unit control 2

The biopsy functions are controlled by the micro controller. In the biopsy unit there are three potentiometers indicating the current needle position.

The values from the poten tiometers ar e A/D con v erted and sent to the micro contr oller. To check the converted values from the A/D converter, the potentiometer values are converted in paralle l by the micro controller.

RS-232 switching 2

To enable RS-232 communication between MAMMOMAT and either MAMMOMAT printer/ service PC or workstation, a relay is used. The rel ay is controlled by the workstation.

CCD camera power supply 2

The biopsy controller conv erts the mains AC voltage to DC voltages. The DC voltages are used by the CCD camera.

LEDs 2

On the biopsy controller printed circuit board , D200, there are a number of LEDs with the following meaning:

• Indication of RAM error

• Indication of PROM error

• Indication of analog/digital conver ter

• Indication of NVM error

• Indication of TxD error

• Selection of RS-232 communication to MAMMOMAT printer/servic e PC or workstation

(SELECT_WS)

• Supply voltages (e.g. 5V_COM, 30V_CC)

For more information on LEDs, see MAMMOMAT 1000/3000/3000 Nova - Opdima r Wiring Diagram.

Workstation 2

The workstation includes the follo w ing parts:

• Main unit, including temporary storage medi a i.e. hard disk

• Monitor

• Keyboard and mouse

• Internal CD drive

• External MO unit i.e. magneto-optical dri ve, used for the permanent storage media and

backup

The workstation is used for:

• Running application software

• Communication with the CCD camera

• Control of MAMMOMAT and biopsy unit

Application software 2

The application software run by the workstation is the main communication interface with the user and units of the Opdimar system.

2 - 4 Functional description

CCD camera communication 2

The camera interface in the workstation main unit sends comma nds to the CCD camera from the workstation and receives the image from the camera. The interface adapts the workstation data bus to RS-422.

The camera interface also supplies t he CCD camera opto couplers with power.

Control of MAMMOMAT and biopsy unit 2

The workstation controls the MAMMOMAT via RS-232 communication. Biopsy calculations are performed by the workstation and target coordinates are sent to

the biopsy unit.

Monitor 2

If the settings of the monitor has changed, reset the default values according to the Monitor manual.

Ex.

NOTICE

If a 21” monitor is inst a lled be sure n ot t o change t he proporti ons between length and width. If this has been done anyway, press the auto sizing and centring button marked with a symbol (Fig. 3) to restore the previous settings.

Fig. 3 Symbol

CCD camera 2

The CCD camera consists of a printed circuit board, CCD sandwich and RS-42 2 interface. When the x-ray beams reach the CCD sandwich, electric energy proportional to the x-ray energy is produced. The produced electrical current is A/D conv erted to digital information and sent to the workstation RAM via an RS-422 interface.

Biopsy unit 2

The biopsy unit is used for performing biopsy examinati ons. The biopsy unit consists of a needle positioning device which is firmly attached to an

18 cm x 24 cm object table with a cut-out contour that is superimposed on the CCD. External stereo diaphragm, needle support and compression plate are also included in the biopsy unit. The biopsy unit can easily be attached to the swiv el arm of the MAMMOMAT.

There are three displays on the biopsy unit front. The displays show spatial deviation of needle tip from the suspect point in x-, y- and z- axis calculated by the workstation.

Three potentiometers monitors the actual position of the needle tip.

Protective measures for CCD camera 3

3 - 1

CAUTION

The camera shall be used within 10230i C. The camera shall be transported or stored within 0240i C.

The CCD camera has to be handled with extreme care, it is very sensitive to mechanical shocks and temperat ure. When not connected do not touch the pins in the camera contacts. Shock and temperature sensors are integrated in the camera.

The CCD camera is sensitive to mechanical shock and shall always be stored in the attaché case, delivered with the system, when disconnected from the biopsy controller.

Protective measures 4

It is very important that any intervention in the equipment shall start with disconnecting it from the power supply with the main circuit br eaker. To prevent accidental triggering of high voltage and radiat ion, set the switch S2 (SS) on board D702 to OFF (lower position, no triggering of the SS relay).

4 - 1

CAUTION

WARNING

When switching off the w o rkstation use the power off procedure described in the Supplement to the Instructions for Use MAMMOMAT 3000 - Opdimar.

Switching off the workstation before the software has been closed down may cause damage to the files on the hard disc.

If the system is only switched off at the control panel or with S2/ D711 in the MAMMOMAT generator, line voltage will still be present at the generator line connection, line filter Z1, Z2, transformer T1, transformer T10 and board D711 (see MAMMOMAT 1000/3000 Nova Wiring Diagram). The Opdimar is switched off separately.

After shut-down of the system, there may still be about 380 V DC present on the intermediate circuit of the MAMMOMAT generator. This will be indicated by LED V24 on board D710. The voltage will drop to less than 30 V within about 3 minutes, the LED goes out at about 30 V.

CAUTION

Siemens-Elema AB Register 5 SPB7-230.061.10 Page 1 of 2 Opdimar Solna, Sweden Rev. 01 09.02 SPS-UD Service

Observe the currently valid guidelines for handling elect ronics endangered by electrostatic discharge.

Use ESD-equipment, ground prior to making contact and place the components on a conductive surface.

The boards contain electrostatic highly sensitive components requiring particular care in their handl ing.

Calibration of the biopsy unit 5

Calibration of the biopsy unit is carried out by using a stereo calibration phantom with targets at fixed positions. By releasing two st ereo pair exposures with a fine needle adjusted to different targets , the system is automatically cal ibrated. F ol low the inst ructions given on the screen during the calibration procedure.

1. Press the Biopsy Calibration button i n the service dialog. The following is shown on the scre en:
