A single-image method is proposed for quantitative phase retrieval in hard X-ray grating
interferometry. This novel method assumes a quasi-homogeneous sample, with a constant …

In recent years, efforts have been made on the information extraction method in x-ray grating-
based phase contrast imaging. Among them, the reverse projection method proposed by PP …

One of the most exciting aspects of the grating based x-ray differential phase contrast (DPC)
acquisition method is the concurrent generation of the so-called dark field (DF) signal, along …

In this abstract we describe the first non-interferometric x-ray phase contrast imaging (PCI)
method that uses only a single-measurement step to retrieve with quantitative accuracy …

A phase imaging method and apparatus are provided, the phase imaging method including
causing a quantum beam from a radiation source to be incident on a detector through a test …

In this paper, a phase retrieval method using the Hilbert transform (HT) and low-rank method
is proposed to obtain differential phase contrast (DPC) imaging. The method has the …

X-ray phase-contrast imaging has attracted much more attention in researches, due to the
better imaging contrast than absorption when the sample is made of light elements …

X-ray tomosynthesis is a pseudo-tomographic imaging method that can partially address the
problem of structural overlap encountered in planar X-ray imaging. All of these …

In X-ray phase contrast imaging, phase retrieval from intensity measurements is the key for
further quantitative analysis and tomographic reconstructions. In this letter, we present a …

For grating interferometer-based x-ray differential phase contrast (DPC) imaging systems,
their noise performance is strongly dependent on both the visibility of the interference fringe …
