Multimodal Intrinsic Speckle-Tracking (MIST) to extract rapidly-varying diffuse X-ray scatter

Samantha J. Alloo, Kaye S. Morgan, David M. Paganin +1

Speckle-based phase-contrast X-ray imaging (SB-PCXI) can reconstruct high-resolution images of weakly-attenuating materials that would otherwise be indistinguishable in conventiona…

Tomographic phase and attenuation extraction for a sample composed of unknown materials using X-ray propagation-based phase-contrast imaging

Samantha J. Alloo, David M. Paganin, Kaye S. Morgan +9

Propagation-based phase-contrast X-ray imaging (PB-PCXI) generates image contrast by utilizing sample-imposed phase-shifts. This has proven useful when imaging weakly-attenuating s…

Directional dark-field implicit x-ray speckle tracking using an anisotropic-diffusion Fokker-Planck equation

Konstantin M. Pavlov, David M. Paganin, Kaye S. Morgan +5

When a macroscopic-sized non-crystalline sample is illuminated using coherent x-ray radiation, a bifurcation of photon energy flow may occur. The coarse-grained complex refractive…

X-ray Multimodal Intrinsic-Speckle-Tracking

Konstantin M. Pavlov, David M. Paganin, Heyang Li +3

We develop X-ray Multi-modal Intrinsic-Speckle-Tracking (MIST), a form of X-ray speckle-tracking that is able to recover both the position-dependent phase shift and the position-de…

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…

Fast three-dimensional phase retrieval in propagation-based x-ray tomography

Darren Thompson, Yakov I. Nesterets, Konstantin M. Pavlov +1

The following paper describes a method for three-dimensional (3D) reconstruction of multi-material objects based on propagation-based X-ray phase-contrast tomography (PB-CT) with p…
