Establishing the reference values
and verifying image quality for
mammography application
(DT 2 Mammo) (optional)
After installation of a new Drystar AXYS and before initial use you must estab-
lish Quality Control aim values. These values will be used as the base line for
comparison when daily Quality Control is done. These values should be deter-
mined again after major service, repair or software update.
The following Quality Control aim values must be determined:
The daily operating density levels. Refer to
erence density levels for mammography application (DT 2 Mammo) (optional)"
on page 108.
Drystar AXYS image geometry. Refer to
ence values for mammography application (DT 2 Mammo) (optional)"
page 112.
Once Quality Control aim values are established you must evaluate the Spatial
Resolution, the Artifact Levels and the Low Contrast Visibility to determine if
the image quality is acceptable. Refer to
tion and Artifact Levels and Low Contrast Visibility for mammography applica-
tion (DT 2 Mammo) (optional)"
The Quality Control aim values, the Spatial Resolution and Artifact Levels and
the Image Geometry values are all recorded on the Quality Control charts. Refer
to "Charts for mammography QC (optional)"
