Description
TEST SPECIMEN FOR COMPUTED RADIOGRAPHY SCANNERS
The CR Phantom can test all the important performance characteristics of a CR scanner system including basic spatial resolution (unsharpness), contrast, MTF, laser beam jitter, scanner slipping and scanner shading. These tests are described in detail in the ASTM E 2445 and EN 14784-1 standards and should be performed periodically to ensure proper and accurate system operation.
