TG18 Test Patterns

TG18 test patterns can be used to evaluate the performance of medical display devices. TG18 test patterns are a part of the larger display assessment methodology developed by TG18 (Technical Group 18) of the AAPM.

The most important test pattern, the TG18-QC test pattern, is based on the original SMPTE test pattern. The TG18-QC pattern is widely used to provide an overall assesment of a monitor's adjustment and calibration.
