Paper Abstract

We proposed that material discriminated X-ray CT with conventional X-ray tube and energy differentiation type 64ch CdTe radiation line sensor. Distribution of Atomic number was obtained by using dual-energy X-ray CT. In this study, problem of conventional X-ray tube was reduced by the collimator and measurement time. So line attenuation coefficient was obtained depend on theory. Atomic number was calculated with two different methods. We could obtain atomic number within about three error margin.
