Quality Check (QC) scans are required to verify and maintain the quality of scan images. All QC
scans use the supplied Gammex 464 Phantom to test image quality against a known spacial profile.
In this process, the Full Helical and Full Axial QC scans adjust system baseline parameters for
quality 120 kV, 100 kV, and 80 kV scans. The Daily Helical and Daily Axial QC scans verify that the
system and current operating conditions continue to match these parameters. For multi-kV QC

Tomography Quality Control Manual. 100 kV and 80 kV portions of QC cycles examine a subset of
