Paper Abstract

X-ray phase imaging can significantly improve image contrast in soft-tissue imaging applications such as mammography where the inherent contrast in conventional attenuation-based imaging is low. A system that employs a stainless steel wire mesh to produce a high-contrast structured illumination pattern reduces the need for source coherence and complex alignments. Phase is reconstructed from distortions in this pattern due to phase-based x-ray deflection. A computational model of this system has been developed that allows exploration of design parameters including source size, mesh period, sample structure, detector pixel size and locations of these system elements. Simulation results are presented and compared with experiment for validation.
