Muti-criterion Optimization Algorithm for X-ray Phase Contrast CT imaging

X-ray phase contrast imaging method is able to show microstructure inside soft tissues with weak absorption in a radiograph mode. X-ray phase contrast CT is being under study. We propose a multi-criterion optimization approach to reconstruct the object from phase contrast images. Our reconstructed results show that the method can differentiate boundary of microstructure of fly very clearly. Comparison of the reconstructed images indicates that this algorithm gives finer resolution and better smoothness over the conventional ones
