Journal ArticleDOI
Low-dose, simple, and fast grating-based X-ray phase-contrast imaging
Peiping Zhu,Kai Zhang,Zhili Wang,Yijin Liu,Xiaosong Liu,Ziyu Wu,Samuel A. McDonald,Federica Marone,Marco Stampanoni +8 more
TL;DR: Compared to the existing phase-stepping approach, the main advantages of this new method dubbed “reverse projection” are not only the significantly reduced delivered dose, without the degradation of the image quality, but also the much higher efficiency.
Journal ArticleDOI
In-situ X-ray computed tomography characterisation of 3D fracture evolution and image-based numerical homogenisation of concrete
Zhenjun Yang,Wenyuan Ren,Rajneesh Sharma,Samuel A. McDonald,Mahmoud Mostafavi,Yelena Vertyagina,Thomas James Marrow +6 more
TL;DR: In this paper, in-situ micro X-ray Computed Tomography (XCT) tests of concrete cubes under progressive compressive loading were carried out to study 3D fracture evolution.
Journal ArticleDOI
Advanced phase-contrast imaging using a grating interferometer
Samuel A. McDonald,Samuel A. McDonald,Federica Marone,Christoph Hintermüller,G. Mikuljan,Christian David,Franz Pfeiffer,Franz Pfeiffer,Marco Stampanoni,Marco Stampanoni +9 more
TL;DR: Differential phase-contrast (DPC) imaging, which uses a grating interferometer and a phase-stepping technique, has been integrated into TOMCAT, a beamline dedicated to tomographic microscopy and coherent radiology experiments at the Swiss Light Source.
Journal ArticleDOI
Non-destructive mapping of grain orientations in 3D by laboratory X-ray microscopy.
Samuel A. McDonald,Péter Reischig,Christian Holzner,Erik Mejdal Lauridsen,Philip J. Withers,Arno Merkle,Michael Feser +6 more
TL;DR: A novel laboratory-based X-ray DCT modality (LabDCT) is described, enabling the wider accessibility of the DCT technique for routine use and in-depth studies of temporal changes in crystallographic grain structure non-destructively over time through ‘4D’ in situ time-lapse studies.
Journal ArticleDOI
Imaging brain amyloid deposition using grating-based differential phase contrast tomography
Bernd R. Pinzer,Matthias Cacquevel,Peter Modregger,Peter Modregger,Samuel A. McDonald,Jean-Charles Bensadoun,Thomas Thuering,Thomas Thuering,Patrick Aebischer,Marco Stampanoni,Marco Stampanoni +10 more
TL;DR: A new experimental imaging setup based on a grating interferometer at a synchrotron X-ray source yields sufficient contrast to detect amyloid plaques and to quantify automatically several important structural parameters, such as their size and their regional density in 3D, on the scale of a whole mouse brain.
