Correlation Between Basic QC and RadiCS
Pattern Check
The patterns used for Basic QC are the same as those used for AAPM. RadiCS determines the
properties to be verified and independently prepares appropriate patterns for each resolution.
TG18-QC This is scaled to match the resolution.

Correlation Between DMG QC Manual and RadiCS
Pattern Check
RadiCS determines necessary test patterns based on the inspection results and generates its own
patterns corresponding to the monitor’s resolution.
TG18-QC Equivalent to the pattern with the same name in the standard. However,
RadiCS-specific scaling is performed in accordance with the monitor
resolution.
TG18-UN80 A pattern solidly filled with white of grayscale 204. The pattern with the
same name in the JESRA has a square frame, but RadiCS does not have
it because it is not necessary for the visual inspection.
