We present a fast algorithm for fully 3D regularized X-ray tomography reconstruction for both
traditional and differential phase contrast measurements. In many applications, it is critical to …

In this paper we introduce a new reconstruction algorithm for X-ray differential phase-
contrast Imaging (DPCI). Our approach is based on 1) a variational formulation with a …

Differential phase-contrast is a recent technique in the context of X-ray imaging. In order to
reduce the specimen's exposure time, we propose a new iterative algorithm that can achieve …

Grating interferometry X-ray differential phase contrast imaging (GI-XDPCI) has provided
enhanced imaging contrast and attracted more and more interests. Currently the low …

Our contribution in this paper is two fold. First, we propose a novel discretization of the
forward model for differential phase-contrast imaging that uses B-spline basis functions. The …

Differential phase contrast computed tomography (DPC-CT) is an x-ray imaging method that
uses the wave properties of imaging photons as the contrast mechanism. It has been …

Purpose: The purpose of this work is to propose a cost function with regularization to
iteratively reconstruct attenuation, phase, and scatter images simultaneously from differential …

Grating-based phase-contrast computed tomography (PCCT) is a promising imaging tool on
the horizon for pre-clinical and clinical applications. Until now PCCT has been plagued by …

This paper describes an algebraic reconstruction algorithm that uses total variation (TV)
regularization for differential phase contrast computed tomography (DPC-CT) using a limited …

Differential X-ray phase-contrast tomography (DPCT) refers to a class of promising methods
for reconstructing the X-ray refractive index distribution of materials that present weak X-ray …
