On optimization of Paganin's method for propagation-based X-ray phase-contrast imaging and tomography
Timur E. Gureyev, David M. Paganin, Ashkan Pakzad +1
Paganin's method for image reconstruction in propagation-based phase-contrast X-ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publ…
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…
Signal-to-noise and spatial resolution in in-line imaging. 2. Phase-contrast tomography
T. E. Gureyev, D. M. Paganin, K. M. Pavlov +2
In the first part of this paper, quantitative aspects of propagation-based phase-contrast imaging (PBI) were investigated using theoretical and numerical approaches, as well as exp…
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.,…
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…
