TL;DR: In this paper, the second moment of the scattering angle distribution can be expressed as the minus logarithm of the visibility degradation of the oscillation curve in grating-based imaging.

TL;DR: In this paper, a feasible method to obtain differential phase-contrast images directly with incoherent x-ray sources, avoiding the Talbot effect, which requires coherent x rays, was described.

TL;DR: In this paper, a vehicle-carried mobile container inspection apparatus is described, which consists of a first box-shaped cabin arranged in the front portion of the chassis and provided with a workroom accommodating a scan control module, an image acquisition module and an operation/inspection module.

TL;DR: In this article, a direct reconstruction algorithm for directional-derivative projections of computed tomography of diffraction enhanced imaging is proposed, which does not require any restoration processing compared with the current two-step methods.

TL;DR: In this article, a relocatable container inspection device, which is constituted by modularized units, is used for inspecting a container, consisting of a first cabin unit including a radiation source for generating a beam of penetration radiation for penetrating the container to be inspected; a second cabin unit included detectors for detecting the beam of penetrating radiation penetrating through the container being inspected and producing corresponding radiographic signals, the second cabin units and the first cabin units being arranged oppositely in both sides of an inspection passage; a gantry unit bridging the first Cabin unit and the second Cabin unit to form a
