2.5.6 Performing the Afssaps / EUREF Calibration Check
(1) Leave the service command session.
(2) Connect the printer network cable to the network outlet at the wall.
(3) Consult the “connectivity release document” for the modality connection to
DRYSTAR AXYS Mammo for the proper modality configuration to print the “TG18-
PQC modified 4” test image.
(4) Print the “TG18-PQC modified 4” test image from the modality.
(5) Measure the 18 density values and enter them in the Afssaps / EUREF
Calibration Check Excel sheet. See Figure 17.

(6) Check column “Deviation compared to DICOM (%)”: All values have to be < 10%.
- If all values are < 10%, the procedure is finished.
- If one (or more) value(s) are
≥
10 %, proceed with next section.
(7) Repeat this step for the other film tray, if the printer has two different DT2 Mammo
film formats loaded (e.g. 8x10” DT2 Mammo and 10x12” DT2 Mammo).
