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 ISO 16371-1 and ASTM E 2445 standards and should be performed periodically to ensure proper and accurate system operation. For easy use of the CR Phantom, a test procedure and the D-Tect Viewer software are available for free download.
To meet the requirements of these standards, the DÜRR NDT CR Phantom includes two duplex wire-type IQIs and measuring points for shading correction positioned in both axis directions (horizontal and vertical). This allows all the required information to be mapped on the imaging plate with a single X-ray exposure – the CR Phantom does not need to be rotated to obtain the data of the second axis, resulting in more accurate test scores and significant time savings.
