TL;DR: This letter reports a new approach on the basis of a grating interferometer that can efficiently yield dark-field scatter images of high quality, even with conventional X-ray tube sources and is fully compatible with conventional transmission radiography and a recently developed hard-X-ray phase-contrast imaging scheme.

TL;DR: It is demonstrated how the soft tissue sensitivity of the technique is increased and in vitro tomographic images of a tumor bearing rat brain sample are shown, without use of contrast agents.

TL;DR: To quantitatively assess the new potential of particularly the grating-based dark-field imaging modality, a mathematical formalism together with a material-dependent parameter, the so-called linear diffusion coefficient, is introduced and it is shown that this description can yield quantitative dark- field computed tomography (QDFCT) images of experimental test phantoms.

TL;DR: In this paper, the authors used grating-based dark-field images of emphysematous vs. healthy lung tissue to monitor the morphological changes that the alveoli network undergoes in the progression of these diseases, which is related to small-angle scattering in the sample.

TL;DR: In-vivo multi-contrast x-ray imaging of a mouse using a compact scanner shows enhanced contrast in regions related to the respiratory system, indicating a possible application in diagnosis of lung diseases.
