TL;DR: In this paper , the authors reported the successful integration of a Talbot-Lau interferometer into a clinical CT gantry and presented dark-field CT results of a human-sized anthropomorphic body phantom, reconstructed from a single rotation scan performed in 1 s.

TL;DR: It is demonstrated that it is possible to successfully reconstruct the linear attenuation coefficient, the refractive index and the linear diffusion coefficient, which is a measure related to ultra-small-angle scattering, using a single measurement per projection angle and without any grating movements.

TL;DR: This study presents high-quality and high-resolution tomographic images of biological samples to demonstrate the experimental feasibility of super-resolution reconstruction and shows the increase in resolution at high sensitivity and with the ability to make quantitative measurements.

TL;DR: These gratings were tested in a three-grating setup with a source operated at 40 kVp and lead to an increase in the detector photon count rate of almost a factor of 4 compared to a set of gratings on silicon substrates, indicating a significant increase in sensitivity and therefore dose efficiency.

TL;DR: This study describes how protein, lipid, and water concentrations in each 3D voxel can be quantified by vector decomposition and demonstrates the potential of phase-contrast imaging as a new analysis tool.
