Multi-contrast x-ray identification of inhomogeneous materials and their discrimination through deep learning approaches
Thomas Partridge, Sukrit S. Shankar, Ian Buchanan +4
Recent innovations in x-ray technology (namely phase-based and energy-resolved imaging) offer unprecedented opportunities for material discrimination, however they are often used i…
Single-shot X-ray Dark-field Tomography
Adam Doherty, Ian Buchanan, Alberto Astolfo +5
X-ray dark-field imaging creates a representation of the sample where contrast is generated by subresolution features within the volume under inspection. These are detected by a lo…
Direct x-ray scattering signal measurements in edge-illumination/beam-tracking imaging and their interplay with the variance of the refraction signals
Ian Buchanan, Silvia Cipiccia, Carlo Peiffer +11
X-ray dark-field or ultra-small angle scatter imaging has become increasingly important since the introduction of phase-based x-ray imaging and is having transformative impact in f…
Cycloidal-spiral sampling for three-modal x-ray CT flyscans with two-dimensional phase sensitivity
G. Lioliou, O. Roche i Morgó, S. Marathe +4
We present a flyscan compatible acquisition scheme for three-modal X-Ray Computed Tomography (CT) with two-dimensional phase sensitivity. Our approach is demonstrated using a "beam…
