A major thrust of medical X-ray imaging is to minimize the X-ray dose acquired by the
patient, down to single-photon sensitivity. Such characteristics have been demonstrated with …

Single-photon detections (SPDs) represent a highly sensitive light detection technique
capable of detecting individual photons at extremely low light intensity levels. This …

When first introduced, single-photon counting detectors reshaped crystallography at
synchrotrons. Their fast readout speed enabled, for example, shutter-less data collection …

This paper presents a new flexible compact multi-modal imaging setup referred to as PEPI
(Photon-counting Edge-illumination Phase-contrast imaging) Lab, which is based on the …

Phase-contrast imaging techniques address the issue of poor soft-tissue contrast
encountered in traditional X-ray imaging. This can be accomplished with the propagation …

Breast computed tomography (BCT) is an emerging application of X-ray tomography in
radiological practice. A few clinical prototypes are under evaluation in hospitals and new …

Spectral micro-CT imaging with direct-detection energy discriminating photon counting
detectors having small pixel size (< 100× 100 µm^ 2) is mainly hampered by: i) the limited …

In this study we compared the image quality of a synchrotron radiation (SR) breast computed
tomography (BCT) system with a clinical BCT in terms of contrast-to-noise ratio (CNR) …

X-ray phase imaging has the potential to dramatically improve soft tissue contrast sensitivity,
which is a crucial requirement in many diagnostic applications such as breast imaging. In …

Objective. Differentiation of breast tissues is challenging in X-ray imaging because tissues
might share similar or even the same linear attenuation coefficients μ. Spectral computed …
