X-ray phase contrast imaging (XPCI) is more sensitive to density variations than X-ray
absorption radiography, which is a crucial advantage when imaging weakly-absorbing, low …

Alkali-silica reaction (ASR) is the result of complex chemical reactions. The exact sequence
of ASR gel formation has yet to be fully understood. One promising hypothesis is that ASR …

Abstract 3D breast modelling for 2D and 3D breast x-ray imaging would benefit from the
availability of digital and physical phantoms that reproduce accurately the complexity of the …

These tutorials introduce some basics of imaging with coherent X-rays, focusing on phase
contrast. We consider the transport-of-intensity equation, as one particular method for X-ray …

A better understanding of functional changes in the cerebral microvasculature following
ischemic injury is essential to elucidate the pathogenesis of stroke. Up to now, the …

We demonstrate a fast, flexible, and accurate paraxial wave propagation model to serve as a
forward model for propagation-based X-ray phase contrast imaging (XPCI) in parallel-beam …

Propagation-based phase-contrast X-ray computed tomography is a valuable tool for high-
resolution visualization of biological samples, giving distinct improvements in terms of …

Using a commercial X-ray tomography instrument, we have obtained reconstructions of a
graded-index optical fiber with voxels of edge length 1.05 µ m at 12 tube voltages. The fiber …

Purpose Advances in additive manufacturing processes are enabling the fabrication of
surrogate bone structures for applications including use in high‐resolution anthropomorphic …

To date, there are very limited noninvasive, regional assays of in vivo lung microstructure
near the alveolar level. It has been suggested that x‐ray phase‐contrast enhanced imaging …
