Biopsy controller

The biopsy controller has three main functions:

•Biopsy unit control

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

•CCD camera power supply

Biopsy unit control

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 potentiometers are A/D converted and sent to the micro controller. To check the converted values from the A/D converter, the potentiometer values are converted in parallel by the micro controller.

RS-232 switching

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

CCD camera power supply

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

LEDs

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 converter

•Indication of NVM error

•Indication of TxD error

•Selection of RS-232 communication to MAMMOMAT printer/service PC or workstation (SELECT_WS)

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

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

CCD camera communication

The camera interface in the workstation main unit sends commands 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 the CCD camera opto couplers with power.

Control of MAMMOMAT and biopsy unit

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.

NOTICE When setting the main voltage on the contact, relate to local main voltage.

CCD camera

The CCD camera consists of a printed circuit board, CCD sandwich and RS-422 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 converted to digital information and sent to the workstation RAM via an RS-422 interface.

Biopsy unit

The biopsy unit is used for performing biopsy examinations.

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 swivel 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 - 1

CAUTION

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

CAUTION

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.

The camera shall be used within 10230i C.

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

Protective measures

4 - 1

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

CAUTION

WARNING

Before switching off the power for the workstation it is important to first shut down the application software (see Logout and turning off the workstation in Supplement to the Instructions for Use MAMMOMAT 3000 - Opdimar).

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.

WARNING

CAUTION

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.

The boards contain electrostatic highly sensitive components requiring particular care in their handling (ground before making contact and place only on a conductive surface, see Technical Information TI 219). After completed hardware service, a protective earth measurement shall be performed.
