Job Card ELE A039 - Compliance with Germany for Detector Dose

1 SUPPLIES
None
2 TOOLS
Set of acrylic plates (stack 4 of the 10 mm plates and the 5 mm plate to yield a thickness of 45 mm)
3 REQUIRED EFFORT
Personnel: 1 Field Engineer
Time: 10 minutes
4 SAFETY PRECAUTIONS
The procedures in this Job Card produce X-rays. Ensure that you take appropriate precautions when
operating with X-rays (for example, stay behind the radiation screen during an X-ray exposure).
5 PREREQUISITES
Activate the display of exposure parameters: select SETUP/GENE/INSTAL/GENE/CONFIG/DISP/YES
on the X-ray Console.
Deactivate the auto decompression: select MEDICAL/DECOMP/DECOMP/NO on the X-ray Console.
6 PROCEDURE
6-1 Objective
This procedure ensures that the Senographe system complies with Detector Dose German regulations.
6-2 First Exposure
1. Make one exposure for each AOP mode, with 45 mm thickness of acrylic on the Bucky compressed
at 4 daN. To yield an acrylic thickness of 45 mm, stack 4 of the 10 mm plates and the 5 mm plate.
2. Note the displayed exposure parameters in the following table:
TABLE 1 -
AOP mode Spectrum (Target/
CNT
STD
Dose
• The radiological thickness must be in the range 4.40 cm to 4.60 cm. If not:
- Repeat the AOP calibration
- Repeat steps 1 and 2.
• The composition must be in the range 45% to 55%. If not:
- Repeat the compression thickness calibration
Calibration on page
- Repeat steps 1 and 2.
Increasing mechanical thickness causes a decrease of composition.
