We report here on recent developments and advances in pore-scale X-ray tomographic
imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid …

In-line phase-contrast X-ray imaging provides images where both absorption and refraction
contribute. For quantitative analysis of these images, the phase needs to be retrieved …

A computer program named ANKAphase is presented that processes X-ray inline phase-
contrast radiographs by reconstructing the projected thickness of the object (s) imaged. The …

X-ray phase-contrast imaging has recently led to a revolution in resolving power and tissue
contrast in biomedical imaging, microscopy and materials science. The necessary high …

Absorption-contrast x-ray imaging serves to visualize the variation in x-ray attenuation within
the volume of a given sample, whereas phase contrast allows one to visualize variations in x …

This review is devoted to a comparative description of the methods for forming X-ray phase-
contrast images of weakly absorbing (phase) objects. These include the crystal …

We demonstrate interface-specific propagation-based x-ray phase retrieval tomography of
the thorax and brain of small animals. Our method utilizes a single propagation-based x-ray …

Over the last few years, differential phase-contrast x-ray computed tomography (PC-CT)
using a hard x-ray grating interferometer and polychromatic x-ray tube sources has been …

RATIONALE AND OBJECTIVES: Diffraction-enhanced imaging (DEI) is a new x-ray imaging
modality that differs from conventional radiography in its use of three physical mechanisms …

When a very-low-absorbing sample is scanned at an x-ray computed tomography setup with
a microfocus x-ray tube and a high-resolution detector, the obtained projection images …
