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

An X-ray Talbot-Lau grating interferometer enables imaging of X-ray phase contrast. It can
measure material transitions that are difficult to observe with traditional attenuation X-ray, for …

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 …

X-ray phase contrast imaging is being investigated with the goal of improving the contrast of
soft tissue. Enhanced edges at material boundaries are characteristic of phase contrast …

X-ray phase contrast imaging (XPCi) methods are sensitive to phase in addition to
attenuation effects and, therefore, can achieve improved image contrast for weakly …

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

Objectives: X-ray computed tomography (CT) using phase contrast can provide images with
greatly enhanced soft-tissue contrast in comparison to conventional attenuation-based CT …

X-ray imaging techniques that capture variations in the x-ray phase can yield higher contrast
images with lower x-ray dose than is possible with conventional absorption radiography …

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 …

Propagation-based imaging is an X-ray phase-contrast method that does not require any
additional optical elements in the imaging system. Instead, phase-contrast effects are …
