Dark-field and directional dark-field on low coherence X-ray sources with random mask modulations: validation with SAXS anisotropy measurements
Clara Magnin, Laurene Quenot, Sylvain Bohic +5
Phase Contrast Imaging (PCI), Dark-Field (DF) and Directional Dark-Field (DDF) imaging are recent X-ray imaging modalities that have demonstrated their interest by providing access…

Single-shot x-ray speckle-based imaging of a single-material object
Konstantin M. Pavlov, Heyang, Li +4
We develop a means for speckle-based phase imaging of the projected thickness of a single-material object, under the assumption of illumination by spatially random time-independent…

Single-Image Geometric-Flow X-Ray Speckle Tracking
David M. Paganin, Helene Labriet, Emmanuel Brun +1
We develop a speckle-tracking method for x-ray phase-contrast imaging, based on the concept of geometric flow. This flow is a conserved current associated with deformation of illum…
