Performing the AEC calibration

The manual you use depends on which acquisition workstation you are using.
•
DROC: Installation Instructions and Startup (DROC) (Chapter: 'Appendix / AEC Cali-
bration')
•
WH AWS: Software, WH AWS VAXXX (Chapter: 'AEC Calibration Tool')

NOTE
Performing the gain calibration
Perform the gain calibration as instructed in the following documentation:
•
DROC: Installation Instructions and Startup (DROC) (Chapter: 'Image Quality / Detec-
tor Calibration')
•
WH AWS: Startup, with WH AWS (Chapter: 'Image Quality / Check Image Quality / Cal-
ibration of detector')
Checking the AEC dose values
The manual you use depends on which acquisition workstation you are using.
•
DROC: Installation Instructions and Startup (DROC) (Chapter: 'Checking the AEC
dose settings')
•
WH AWS: Startup, with WH AWS (Chapter: 'Checking the AEC dose settings')

Performing the QC tests

1. Test 12: 'Mean glandular dose'
2. Test 16: 'AEC testing'

Final procedures

1. Mount the service cover on the back of the MAMMOMAT.
2. Check the protective ground resistance.

Replacing basic unit electrical assemblies
The 'Dark Offset' measurements can be skipped, since the 'Brick
AEC Array Dark Offset' and the 'Brick AEC Array Mag Offset' val-
ues have to be set to '0'.
The AEC calibration can be shortened if you know the 'mAs' value
to be used for the 'goal table'.
You should find the 'mAs' value in the technical binder in the 'Prüf-
protokoll' (test protocol).
If you know the 'mAs' value, you can skip the 'Half Value Layer -
HVL' and 'Entrance Skin Exposure - ESE' measurements and start
directly with 'Generating the goal tables'.
