Abstract:	The conventional computerized tomography reconstructs the object by using the projection images which are imaged based on the absorption of different materials to X-ray. In the recent years, X-ray phase-contrast CT technique has been developed rapidly. DEI method is one of the three phase-sensitive X-ray imaging technique which can be used for CT. DEI method can extract sample’s refraction, absorption and scattering information method by using an analyser crystal. The paper discusses the CT reconstruction criteria and reconstructs two sample’s based on the refraction information. The reconstructed result is better than that of the absorption CT method. DEI-CT is a powerful method for use in clinical tomography and in material science.
