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…
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…
In vivo 4D x-ray dark-field lung imaging in mice
Ying Ying How, Nicole Reyne, Michelle K. Croughan +14
X-ray dark-field imaging is well-suited to visualizing the health of the lungs because the alveoli create a strong dark-field signal. However, time-resolved and tomographic (i.e.,…
Separating edges from microstructure in X-ray dark-field imaging: Evolving and devolving perspectives via the X-ray Fokker-Planck equation
Samantha J. Alloo, David M. Paganin, Michelle K. Croughan +3
A key contribution to X-ray dark-field (XDF) is X-ray diffusion by sample structures smaller than the imaging system's spatial resolution. However, some XDF techniques report that…
