The Phantom has been designed to evaluate the imaging capabilities of 3D X-ray imaging modalities in the x/y-plane. CT-scanners low and medium contrast resolution capabilities can be obtained by a single scan using axial images and coronal reformations. The phantom visualizes the impact of all scan, image reconstruction, and display parameters.

Four series of different contrast step cylinders with diameter varying from 2 mm to 8 mm and a large zylinder of 15 mm are located in the 100 mm diameter cylindrical body of homogeneous tissue- equivalentmaterial.
