Abstract

The aim of present work is application of novel single photon counting system for detection of gamma-rays in CT using semiconductor radiation detector based on semi-insulating (SI) GaAs compound A simple positioning test system consisting of two stepper motors with Am-241 gamma source of 60 keV photons and single SI GaAs radiation detector operated in single photon counting mode is used for taking CT projections. First, rather preliminary results of CT reconstruction applied to imaging of inner structure of a small phantom using developed reconstruction algorithms is demonstrated.
