TL;DR: In this paper, it was shown that a distribution of micrometer-sized calcifications in the human breast which are not visible in clinical x-ray mammography at diagnostic dose levels can produce a significant dark-field signal in a grating-based xray phase-contrast imaging setup with a tungsten anode xray tube operated at 40 kVp.
Journal ArticleDOI
Noise in x-ray grating-based phase-contrast imaging.

TL;DR: The authors used a least squares fitting algorithm to calculate the noise behavior of the three quantities absorption, differential phase, and dark-field image and found that the variance of the reconstructed phase is only dependent of the total number of photons used to generate the phase image and the visibility of the experimental setup.
Journal ArticleDOI
Grating-based darkfield imaging of human breast tissue.

Fasching,Wilhelm Haas,Arndt Hartmann,Thilo Michel,Georg Pelzer,Marcus Radicke,Claudia Rauh,Jens Rieger,André Ritter,Rüdiger Schulz-Wendtland,Michael Uder,David L. Wachter,Thomas Weber,Evelyn Wenkel,Lukas Wucherer +19 more
TL;DR: Comparison with the histomorphometric image proofs that the darkfield signal correlates with a tumor region containing small calcification grains of 3 to 30μm size, which reveals considerably higher contrast than those observed in digital mammography.
Journal ArticleDOI
Projection angle dependence in grating-based X-ray dark-field imaging of ordered structures
Florian Bayer,Simon Zabler,Christian Brendel,Georg Pelzer,Jens Rieger,André Ritter,Thomas Weber,Thilo Michel,Gisela Anton +8 more
TL;DR: This contribution attempts to extend existing models for 2D projections to 3D data by analyzing dark-field contrast tomography of anisotropically structured materials such as carbon fiber reinforced carbon (CFRC).
Journal ArticleDOI
Simulation framework for coherent and incoherent X-ray imaging and its application in Talbot-Lau dark-field imaging
André Ritter,Peter Bartl,Florian Bayer,Karl C. Gödel,Wilhelm Haas,Thilo Michel,Georg Pelzer,Jens Rieger,Thomas Weber,Andrea Zang,Gisela Anton +10 more
TL;DR: A simulation framework for coherent X-ray imaging, based on scalar diffraction theory, is presented and the dark-field signal of densely packed PMMA microspheres is predicted.
