Grating-based x-ray dark-field mammography: Assessing complementary imaging information in simple cystic lesions and typical fibroadenoma. [PDF]
Med PhysAbstract Background A significant proportion of false positive recalls of mammography‐screened women is due to benign breast cysts and simple fibroadenomas. These lesions appear mammographically as smooth‐shaped dense masses and require the recalling of women for a breast ultrasound to obtain complementary imaging information.

High-speed quantitative X-ray multi-contrast imaging with deep learning based modulated pattern analysis. [PDF]
J Synchrotron RadiatThis work presents a neural‐network framework that accelerates X‐ray multi‐contrast imaging—simultaneously delivering absorption, phase, and dark‐field, while maintaining high spatial resolution, and outperforms correlation‐based methods in speed, achieving a favorable balance between resolution and throughput.

Correction for mechanical inaccuracies in a scanning Talbot-Lau interferometer
IEEE Transactions on Medical Imaging, 2022 <p>Grating-based X-ray phase-contrast and in particular dark-field radiography are promising new imaging modalities for medical applications. Currently, the potential advantage of dark-field imaging in early-stage diagnosis of pulmonary diseases in humans is being investigated.

Increased spatial coherence length from an asymmetric crystal reflection at grazing exit. [PDF]
J Synchrotron RadiatA multiple crystal diffraction arrangement with a final asymmetric crystal diffracting at grazing exit was found to yield a 76% longer spatial coherence length compared with that for a beam directly exiting a double‐crystal monochromator.Coherent X‐ray imaging is an active field at synchrotron sources.

From classical xenon fringes to hydrogen interferometry
New Journal of Physics, 2020 A setup with three equally spaced transmission gratings can be described as a moiré deflectometer in the classical regime and as a Talbot–Lau interferometer in the quantum regime.

Matter-wave interference of a native polypeptide
Nature Communications, 2020 Matter-wave interferometry of complex molecules is challenging due to difficulties in preparing and detecting molecular beams. Here the authors demonstrate quantum behavior of a polypeptide using matter-wave interference in an all-optical time-domain ...

Modeling Vibrations of a Tiled Talbot-Lau Interferometer on a Clinical CT
IEEE Transactions on Medical Imaging, 2023 X-ray computed tomography (CT) is an invaluable imaging technique for non-invasive medical diagnosis. However, for soft tissue in the human body the difference in attenuation is inherently small. Grating-based X-ray phase-contrast is a relatively novel imaging method which detects additional interaction mechanisms between photons and matter, namely ...
