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.
