Test Objects for quality control of computer tomography installations 

The CATPHAN test object's design includes many exclusive features that make it easy to achieve perpendicular alignment. As all of the test sections are arranged at prescribed intervals from the first module, operators can quickly scan all test sections in a single sequence, eliminating the need to reposition the phantom for each section. The modular design allows test modules to be interchanged. A wide range of modules for different tasks and installations are available.
