The Phantom has been designed to evaluate the imaging capabilities of a CT scanner in the x/y-plane as well as in the axial-plane. The CTs low-contrast resolution capabilities can be obtained by a single spiral scan using axial images and coronal reformations. The phantom visualizes the impact of all scan, image reconstruction, and display parameters.

In order to mimic imaging conditions in either head or body applications, a contrast of -10 HU or -20 HU can be ordered. Other contrast levels are available on request.

Two series of different low-contrast cylinders with diameter varying from 5 mm to 15 mm are located in the 100 mm diameter cylindrical body of homogeneous tissue-equivalentmaterial.
