High-energy X-ray phase-contrast CT of an adult human chest phantom
Jannis N. Ahlers, Lorenzo D'Amico, Henriette Bast +15
Propagation-based phase-contrast X-ray imaging is a promising technique for in~vivo medical imaging, offering lower radiation doses than traditional attenuation-based imaging. Prev…

Single-exposure X-ray dark-field imaging via a dual-energy propagation-based setup
Jannis N. Ahlers, Konstantin M. Pavlov, Marcus J. Kitchen +10
X-ray dark-field imaging visualises scattering from sample microstructure, and has found application in medical and security contexts. While most X-ray dark-field imaging technique…

Correcting directional dark-field x-ray imaging artefacts using position-dependent image deblurring and attenuation removal
Michelle K Croughan, David M Paganin, Samantha J Alloo +4
In recent years, a novel x-ray imaging modality has emerged that reveals unresolved sample microstructure via a "dark-field image", which provides complementary information to conv…
