6 Panoramic and 3D calibrations and adjustments
89
Artefacts
This check is carried out visually. Person with experience
on interpreting 3D images should perform the check.
Examine the axial slices of 3D QC volume taken in the
previous QC steps. Be aware of artefacts which do not
originate from the object or from the projection conditions.
Please note that there will be some circles drawn in the
volume to indicate areas used for 3D QC program result
calculations.
Requirements:
Absence of artefacts, except for those that may be
expected due to phantom or projection conditions.
Examples:
Acceptable, shadowing may appear around straight
horizontal material interfaces.
