Image Artifacts
A.2
Even with a carefully manufactured, calibrated and maintained
CT system, patterns can sometimes appear in images which are
not part of the computed tomography image. Such patterns are
called artifacts.
A.2
For best image quality results, we strongly recommend to posi-
tion the patient such that the organ to be examined is in the
center of the scan field. Exceptions are examinations of the
aorta or the trachea, which should not be positioned in the very
center in order to avoid ring artifacts.
A.2
Artifacts can have various causes which can in general be
divided into 2 groups: measurement related artifacts and sys-
tem-related artifacts.
