Abstract

Radiation source and detector arrangement for a differential phase contrast CT scanner, in which the detector tiles are placed asymmetrically such that direct rays, which hit gaps between tiles are sampled by tile centers for the complementary rays. This may provide for good image quality without any approximate processing.
