Using Monte-Carlo method combined with diffraction theory of wave optics, in-line diffractive phase-contrast imaging of 3D samples with partially coherent hard x-ray has been simulated. The primary microcosmic interactions of medical-energy x-ray within matter, including photoabsorption, Compton scattering and coherent scattering, are taken into account in the Monte-Carlo simulation. A diffraction processing based on Fresnel diffraction theory is carried out to simulate the macroscopic diffraction effect. A comparison with experiment results has also been performed.
