Paper Abstract

Statistical iterative reconstruction methods have come to the forefront of CT research in recent years, as they have the ability to incorporate the statistical fluctuations in CT measurements into the image reconstruction process. While statistical iterative reconstruction methods have been found to be beneficial in CT imaging, they have not been extensively investigated or applied in other new and promising CT imaging techniques, such as x-ray differential phase contrast computed tomography (DPC-CT). The purpose of this study is to investigate and apply statistical image reconstruction to DPC-CT to reduce streaking artifacts caused by strong small-angle scattering objects.
