Clinical radiography has traditionally been based on contrast obtained from absorption
when X-rays pass through the body. The contrast obtained from traditional radiography can …

Phase-contrast imaging is one of the standard X-ray imaging methods at synchrotron
beamlines and has already proven to be beneficial for soft-tissue visualization. However …

We recently proposed a method for retrieving absorption and phase properties of samples
using a set of spectral x-ray measurements obtained in phase enhanced geometries. The …

Phase-contrast x-ray computed tomography (CT) is an emerging imaging technique that can
be implemented at third-generation synchrotron radiation sources or by using a microfocus x …

We report on a preliminary laboratory based x-ray phase-contrast imaging system capable
of achieving two-directional phase sensitivity, thanks to the use of L-shaped apertures. We …

X-ray phase-contrast imaging and tomography make use of the refraction of X-rays by the
sample in image formation. This provides considerable additional information in the image …

X-ray phase-contrast imaging is an effective approach to drastically increase the contrast
and sensitivity of microtomographic techniques. Numerous approaches to depict the real …

Current clinical x-ray imaging is based on the attenuation contrast. In order to better explore
the phase-contrast inherent in tissue, we propose a dual detector approach for …

A single-projection based phase retrieval method based on the phase attenuation duality
principle (PAD) was used to compare the spatial resolution of the acquired phase sensitive …

We describe a quantitative phase imaging process using an x-ray laboratory-based source
with an extremely broad bandwidth spectrum. The thickness of a homogeneous object can …
