X-ray dark-field imaging from intensity flow: A Fokker-Planck approach to grating interferometry
Samantha J. Alloo, Florian Schaff, Regine Gradl +3
Grating interferometry is a promising diagnostic technique that enables simultaneous acquisition of three complementary, synergistic X-ray images: transmission, differential phase,…
Quantitative Stain Mapping in X-ray Virtual Histology
Dominik John, David M. Paganin, Marie-Christine Zdora +14
Virtual histology is an emerging field in biomedicine that enables three-dimensional tissue visualization using X-ray micro-computed tomography. However, the method still lacks the…
Low-exposure, high-quality multimodal speckle X-ray imaging via an intrinsic gradient-flow approach
Jayvan Liu, Samantha J. Alloo, Max Langer +1
We present a new approach for retrieving dark-field, phase shift, and attenuation images from speckle-based X-ray imaging data. Speckle-based X-ray imaging (SBXI) exploits sample-i…
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…
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…
Tomographic phase and attenuation extraction for a sample composed of unknown materials using X-ray propagation-based phase-contrast imaging
Samantha J. Alloo, David M. Paganin, Kaye S. Morgan +9
Propagation-based phase-contrast X-ray imaging (PB-PCXI) generates image contrast by utilizing sample-imposed phase-shifts. This has proven useful when imaging weakly-attenuating s…
