چکیده انگلیسی
We have developed dual-energy X-ray CT (DXCT) using monochromatic X-ray beams. From the DXCT, we can obtain distributions of an electron density and an effective atomic number in a human body. Especially, the electron density is very important for the heavy-ion radiotherapy. Now, we adopted the CdTe array to this detector system to know the energy of incident photons as well as detect the position and the number of photons. We carry out the experiment of the DXCT with CdTe array at the beamline of KEK. The preliminary result of the experiments and the feasibility of a quantitative polychromatic X-ray CT as an advanced method of this method are shown in this study.
