CR Phantom is used to test all relevant parameters of CR Scanner systems including basic spatial resolution, unsharpness, contrast, MTF, laser beam jitter, scanner slipping and shading. These tests are performed periodically according to ASTM E 2445-14, ISO 16371-1 and EN 14784-1 standards.
The Kowotest CR Phantom exceeds these standards by including two Duplex wire type IQIs. Measuring points for shading correction are arranged in both axis directions – panorama and landscape. All required information is mapped on the image plate with a single X-ray exposure so there is no need to rotate the CR Phantom to receive information from the second axis. This results in more accurate test scores and significant time savings.
Three Duplex IQI's available: D13 (Standard Resolution), D15 (High Resolution), and D17 (Ultra High Resolution)
