Purpose: In this work, the authors investigate how beam hardening affects the image
formation in x‐ray phase‐contrast imaging and consecutively develop a correction algorithm …

Purpose: Grating‐based x‐ray phase‐contrast imaging is a fast developing new modality not
only for medical imaging, but as well for other fields such as material sciences. While these …

We present a theoretical and experimental comparison of three X-ray phase-contrast
techniques: propagation-based imaging, analyzer-based imaging and grating …

Purpose: The purpose of this study is to develop a single‐shot version of the grating‐based
phase contrast x‐ray imaging method and demonstrate its capability ofin vivo animal …

Phase sensitive X-ray imaging methods can provide substantially increased contrast over
conventional absorption-based imaging and therefore new and otherwise inaccessible …

Grating-based differential phase-contrast imaging has proven to be feasible with
conventional X-ray sources. The polychromatic spectrum generally limits the performance of …

In this work, a characterization and optimization of the grating-based X-ray imaging
technique is presented. The investigations are introduced by analytical considerations, are …

Phase-contrast imaging using conventional polychromatic x-ray sources and grating
interferometers has been developed and demonstrated for x-ray energies up to 60 keV …

Purpose: To investigate the properties of tomographic grating‐based phase contrast
imaging with respect to its noise power spectrum and the energy dependence of the …

The relative phase‐contrast factor (RPF) represents a quantitative measure of the phase‐
contrast transfer in x‐ray in‐line phase‐contrast imaging. The larger the modulus of is, the …
