Image shows artifacts

Details

An exposure is performed and the image on the NX

workstation shows lines and banding artifacts.

Cause

The exposure time exceeded the integration time of the

DR detector (configured during installation).

Brief Solution

Depending on the frequency of the problem, take

following measures:

If this situation is exceptional and can be justified by

the high compression thickness or by the type of

examination, try to reduce the exposure time on the

X-ray system.

Perform a typical flat field exposure to check the

general image quality.

Contact your local service representative, who can

extend the integration time of the DR detector.
