Phase Retrieval of X-ray Phase Contrast Imaging Based on Iterative Algorithm
Phase retrieval problem is essential in the field of X-ray phase contrast imaging. Phase information is retrieved from measured intensity data. The error-reduction iterative algorithm is employed to recover phase, with spatial constrains and measured intensity data in the detector plane. Both in the numerical simulation and real imaging data test, the iterative algorithm is verified that it converges steadily.
