Abstract: Phase-Sensitive Region-of-Interest Computed Tomography

X-ray Phase-Contrast Imaging (PCI) is a novel imaging technique that can be implemented with an grating interferometer. PCI is compatible with clinical X-ray equipment, and yields in addition to an absorption image also a differential phase image and a dark- field image. Computed Tomography (CT) of the differential phase can in principle provide high-resolution soft-tissue contrast.
