DRYSTAR 5500/5503 REFERENCE MANUAL
Establishing the image geometry reference values for mammography appli-
cation (DT 2 Mammo) (optional)
To establish the image geometry reference values, proceed as follows:
1 Print the QC mammography test image or use the previously printed test image.
You should obtain an image looking like this (without the dimensions A and B):
QC mammography test image
2 To determine the reference values for geometry, measure the distances A and B
of the geometric square on the test image.
Make sure to measure distance A from the left edge of the left line to the
right edge of the right line and distance B from the upper edge of the
upper line to the lower edge of the lower line.
We strongly recommend using a 30 cm (12-inch) machinist scale with 0.5
mm divisions (1/64 inch).
