Paper Abstract

Maximum-likelihood estimation is an important method of inference. Recently, maximum-likelihood techniques have been successfully applied to absorption tomography of weakly as well as strongly absorbing materials. In this presentation we generalize this method to the phase contrast tomography, which combines the phase estimation and tomography. Unlike the standard phase fitting followed by the filtered back-projection, the developed procedure gives reasonable results also when applied to very noisy data or data consisting of only a few measured projections. The proposed method could therefore considerably shorten measuring times in applications involving low intensity beams, such as phase tomography with low intense X-ray beams or neutrons.
