Paper Abstract

A number of examinations were performed on the VolumeScope Compton scatter tomographic device and a CT scanner (Siemens Somatom Plus 4) using an anthropomorphic tissue-equivalent heterogeneous phantom simulating a human body. Three main parts of the phantom were under examination: head, thorax and pelvis. An absorbed dose in the phantom was measured by LiF thermoluminescent detectors. The CT scanner demonstrated better space resolution in cross-plane and lower statistical noise. On the other hand, absorbed dose due to CT scanning is about 20 times higher at the same points of measurement. Examples of reconstructed images are presented.
