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,…
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…
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…
Demonstrating a family of X-ray dark-field retrieval approaches on a common set of samples
Samantha J. Alloo, Ying Ying How, Jannis N. Ahlers +3
Sensitive to scattering from unresolved sample structures, the dark-field channel in full-field X-ray imaging provides complementary information to that offered by conventional att…
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…
Stabilizing Laplacian Inversion in Fokker-Planck Image Retrieval using the Transport-of-Intensity Equation
Samantha J Alloo, Kaye S Morgan
X-ray attenuation, phase, and dark-field images provide complementary information. Different experimental techniques can capture these contrast mechanisms, and the corresponding im…
