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 …

X-ray imaging is a standard tool for the non-destructive inspection of the internal structure of
samples. It finds application in a vast diversity of fields: medicine, biology, many engineering …

Although early demonstration dates back to the mid-sixties, x-ray phase-contrast imaging
(XPCI) became hugely popular in the mid-90s, thanks to the advent of 3rd generation …

Conventional radiography produces a single image of an object by measuring the
attenuation of an x-ray beam passing through it. When imaging weakly absorbing tissues, x …

X-ray imaging has been boosted by the introduction of phase-based methods. Detail
visibility is enhanced in phase contrast images, and dark-field images are sensitive to …

Wavefront-marking X-ray imaging techniques use eg, sandpaper or a grating to generate
intensity fluctuations, and analyze their distortion by the sample in order to retrieve …

Numerous advances have been made in X-ray technology in recent years. X-ray imaging
plays an important role in the nondestructive exploration of the internal structures of objects …

Phase-based approaches can revolutionize X-ray imaging and remove its main limitation:
poor image contrast arising from low attenuation differences. They exploit the unit decrement …

When an X-ray wave traverses an object, its amplitude and phase change, resulting in
attenuation, interference, and refraction, and in phase-contrast X-ray imaging (PCI) these …

Ever since the first demonstration of phase contrast imaging (PCI) in the 1930s by Frits
Zernike, people have realized the significant advantage of phase contrast over conventional …
