Abstract

Edge illumination is an emerging X-ray phase contrast imaging technique, which has been successfully transferred from synchrotron facilities to lab-based X-ray systems. Rather than installing a dedicated phase contrast system, our goal is to enable phase contrast imaging in a highly flexible X-ray CT system, FleXCT, a novel scanning system consisting of ten motorized axes. These axes allow movements of not only the sample stage, but also the source and detector. To enable phase contrast imaging, two gratings have to be incorporated in the FleXCT system. In this work, we report on the procedure to determine the optimal grating parameters, relying on numerical simulations. Optimal parameter values are presented for both FleXCT gratings.
