Paper Abstract

In X-ray phase-contrast tomography imaging studies, the object of interest may be larger than the field of view (FOV) of the imaging system, resulting in a set of truncated tomographic projections. In this work, we adapt recent advancements in conventional reconstruction theory to X-ray phase-contrast tomography, and demonstrate that the Laplacian of the refractive index distribution can be reconstructed exactly within certain regions-of-interest from knowledge of truncated phase-contrast projection data.
