The digital tomosynthesis group contains X-ray modality settings to
control the X-ray system movement, the X-ray exposure parameters and
the image processing for the reconstruction.

WARNING:
The negative effect of movement on the quality of the
reconstruction sequence can be recuded by selecting the
narrower X-ray tube sweep angle.
The X-ray tube sweep angle can be set to 15 degrees or 22 degrees. If the
bodypart that is examined is likely to move (e.g. by breathing), a narrower
sweep angle is recommended, as its workflow has a shorter duration.
Below are recommended settings of SID and sweep angle for typical
examinations:

Chest 150 mm 15 degrees
Hand, foot 115 mm 22 degrees
