Checking Opdose - Siemens MAMMOMAT Novation DR Manual

Checking dose settings

Checking OPDOSE

The OPDOSE values are checked in this chapter.
In AUTO mode the system suggests an appropriate program (kV, Anode/Filter combina-
tion) corresponding to a specific breast thickness. The new, suggested program is indi-
cated by a blinking LED, whereas the previously used program is shown by a
continuously lighted LED.
Please see the Instructions of Use (SPB7-250.620.01...) for the correct OPDOSE val-
ues.
Changes can be made with the MAMMOMAT stand service software:
Configuration -> Miscellaneous -> Auto limits.
A special setting can be stored for each wing, thus the measurement has to be performed
for the detector wing and the OPDIMA wing.
Proceed as follows for the "detector wing":
1. Select the detector wing. dr is then displayed on the control console.
2. Mount a 18x24 cm compression plate.
3. Select a thickness of calibration plexi (part no. 65 61 240) that is within the thickness in-
terval of the program to be tested.
4. Select AUTO on the control panel.
5. Place the calibration plexi on the object table and compress to 6 kg or more.
6. Check that the correct program is blinking on the control panel. Select the program by
pressing the corresponding program button on the control panel.
7. Repeat the procedure described in steps 3-6 for the other programs used.

8. Record the measured values in the "Installation Protocol" (SPB7-250.813.01...).
Proceed as follows for the "OPDIMA wing":
1. Select the OPDIMA wing. As a result, OP is displayed on the control console.
2. Mount the spot 1.0 compression plate.
3. Select a thickness of calibration plexi (part no. 65 61 240) that is within the thickness in-
terval of the program to be tested.
4. Select AUTO on the control panel.
5. Place the calibration plexi on the object table and compress to 6 kg or more.
6. Check that the correct program is blinking on the control panel. Select the program by
pressing the corresponding program button on the control panel.
7. Repeat the procedure described in steps 3-6 for the other programs used.
