Abstract

X-ray differential phase-contrast tomography (DPCT) is a method for reconstructing the spatial distribution of the X-ray refractive index within an object from knowledge of differential projection data. Assuming geometrical optics wave propagation, these data describe the angles by which the probing optical beams are deflected by the object due to refraction. Phase-sensitive X-ray imaging methods such as diffraction enhanced imaging can measure the required beam-deflection data, and are being actively developed for medical imaging applications. In this work, we investigate and demonstrate the applicability of algorithms recently developed for conventional tomography for obtaining region-of-interest images in DPCT from knowledge of truncated differential projection data. A preliminary numerical study is conducted to validate and demonstrate the proposed reconstruction algorithm.
