Look-Up Table-Correction for Beam Hardening-Induced Signal of Clinical Dark-Field Chest Radiographs
Maximilian E. Lochschmidt, Theresa Urban, Lennard Kaster +4
Background: Material structures at the micrometer scale cause ultra-small-angle X-ray scattering, e.g., seen in lung tissue or plastic foams. In grating-based X-ray imaging, this c…
Influence of Medical Foreign Bodies on Dark-Field Chest Radiographs: First experiences
Lennard Kaster, Henriette Klein, Alexander W. Marka +7
Objectives: Evaluating the effects and artifacts introduced by medical foreign bodies in clinical dark-field chest radiographs and assessing their influence on the evaluation of pu…
X-ray dark-field signal reduction due to hardening of the visibility spectrum
Fabio De Marco, Jana Andrejewski, Theresa Urban +6
X-ray dark-field imaging enables a spatially-resolved visualization of ultra-small-angle X-ray scattering. Using phantom measurements, we demonstrate that a material's effective da…
