Phase sensitive x-ray imaging extends standard x-ray microscopy techniques by offering up
to a thousand times higher sensitivity than absorption-based techniques. If an object is …

We describe a direct quantitative phase reconstruction approach using an X-ray laboratory-
based source. Using a single phase-contrast image from each tomographic projection we …

A well‐known problem in x‐ray microcomputed tomography is low sensitivity. Phase contrast
imaging offers an increase of sensitivity of up to a factor of in the hard x‐ray region, which …

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 …

The reconstruction problem in in-line X-ray Phase-Contrast Tomography is usually
approached by solving two independent linearized sub-problems: phase retrieval and …

Phase contrast imaging has been of growing interest in the biomedical field, since it
provides an enhanced contrast compared to attenuation-based imaging. Actually, the phase …

X-ray propagation-based phase-contrast imaging is an attractive phase-sensitive imaging
technique that has found applications in many research fields. Here, we report the …

We introduce theoretically and demonstrate experimentally a contrast transfer function
based phase retrieval algorithm that reconstructs the projected thickness of an …

X‐ray phase tomography aims at reconstructing the 3D electron density distribution of an
object. It offers enhanced sensitivity compared to attenuation‐based X‐ray absorption …

The attenuation of x-rays in a material forms the basis of x-ray radiography and tomography.
By measuring the transmission of the x-rays over a large amount of raypaths, the three …
