CR Phantom Type I + II
Test Phantom for Qualification of Image Plate Scanner Systems (CR)
CR Phantom enables to test all relevant parameters of CR Scanner systems and Imaging Plates (IP) like Basic Spatial Resolution, MTF, Contrast Sensitivity, Blooming, Laser Jitter, Scanner Slippage, Shading, Erasure and more. These tests required and described in detail in standards ASTM E2445 and ISO 16371-1 have to be performed periodically for checking process control and long-term-stability.
The KOWOTEST CR Phantom type I exceed these standards by including two Duplex Wire Type IQIs and measuring points for Shading in both axes – portrait and landscape. All required information is mapped on the Imaging Plate with a single X-ray exposure. Phantom must not be rotated to generate information of second axis. This results in higher accuracy and significant time savings.
