Phase-contrast micro-CT for intra-operative breast tumour margin assessment using a microfocus x-ray source and photon-counting detector
Michelle K. Croughan, Timur E. Gureyev, Jane Fox +5
Objective: Intra-operative tumour margin assessment during breast-conserving surgery requires rapid, high-resolution imaging of excised tissue, allowing the surgical team to take a…
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…
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…
Directional dark-field retrieval with single-grid x-ray imaging
Michelle K Croughan, Ying Ying How, Allan Pennings +1
Directional dark-field imaging is an emerging x-ray modality that is sensitive to unresolved anisotropic scattering from sub-pixel sample microstructures. A single-grid imaging set…
Fast implicit diffusive dark-field retrieval for single-exposure, single-mask x-ray imaging
Mario A. Beltran, David M. Paganin, Michelle K. Croughan +1
Complementary to conventional and phase X-ray radiography, dark-field imaging has become central in visualizing diffusive scattering signal due to the spatially-unresolved texture…
Accurate measures of regional lung air volumes from chest X-rays of small animals
D. W. O'Connell, K. S. Morgan, G. Ruben +10
We present a robust technique for calculating regional volume changes within the lung from X-ray radiograph sequences captured during ventilation, without the use of computed tomog…
Precise phase retrieval for propagation-based images using discrete mathematics
J. A. Pollock, K. S. Morgan, L. C. P. Croton +5
The ill-posed problem of phase retrieval in optics, using one or more intensity measurements, has a multitude of applications using electromagnetic or matter waves. Many phase retr…
