Phase-contrast x-ray imaging (PCI) is an innovative method that is sensitive to the refraction
of the x-rays in matter. PCI is particularly adapted to visualize weakly absorbing details like …

Breast imaging is one of the most demanding and delicate radiological applications.
Mammography is the primary diagnosis tool in breast cancer detection and national …

In this work, we developed a new theoretical framework using wave optics to explain the
working mechanism of the grating based X-ray differential phase contrast imaging (XPCI) …

Grating-based x-ray differential phase contrast (DPC) imaging has shown huge potential.
For broad applications, it is essential that the key components are low-cost, especially the …

Talbot–Lau grating interferometer (TLGI) has great advantages in x-ray imaging contrasts,
especially for low-Z materials, over conventional absorption contrast. A microstructured array …

The X-ray phase contrast imaging using a Talbot–Lau grating interferometer (GI) can
achieve high resolution of low-contrast objects such as soft tissues. The periodic …

The high-aspect-ratio silicon grating (HARSG) is an important X-ray optical device that is
widely used in X-ray imaging and spectrum detection systems. In this paper, we propose a …

Purpose: We investigate an analyzer-less x-ray interferometer with a spatially modulated
phase grating (MPG) that can deliver three modalities (attenuation image, phase image, and …

Background To obtain phase-contrast X-ray images, single-grid imaging systems are
effective, but Moire artifacts remain a significant issue. The solution for removing Moire …

Among X-ray phase-contrast techniques, grating-based X-ray differential phase contrast
(DPC) imaging using conventional X-ray tube sources is the most prominent one for …
