Noise magnitude in conventional attenuation X-ray tomography (CT) is strongly dependent
on the pixel size and/or the geometrical magnification, thereby limiting the possibility of …

We report the results of a systematic study of phase-contrast x-ray computed tomography in
the propagation-based and analyser-based modes using specially designed phantoms and …

Three phase-retrieval algorithms, based on the transport-of-intensity equation and on the
contrast transfer function for propagation-based imaging, and on the linearized geometrical …

Purpose X‐ray phase‐contrast tomography (PCT) is a rapidly emerging imaging modality for
reconstructing estimates of an object's three‐dimensional x‐ray refractive index distribution …

Phase-contrast x-ray computed tomography (PCCT) is currently investigated as an
interesting extension of conventional CT, providing high soft-tissue contrast even if …

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 …

X-ray phase-contrast tomography can significantly increase the contrast-resolution of
conventional attenuation-contrast imaging, especially for soft-tissue structures that have very …

Purpose This article is aimed at comparing edge illumination (EI) x‐ray phase contrast
computed tomography (PCT) and conventional (attenuation‐based) computed tomography …

We analyze the signal and noise propagation of differential phase-contrast computed
tomography (PCT) compared with conventional attenuation-based computed tomography …

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 …
