Fast Ptychographic Near-Field Computed Tomography
Sami Wirtensohn, Silja Flenner, Imke Greving +13
Near-field X-ray ptychography enables quantitative three-dimensional imaging with nanometer-scale resolution, but its broader application is limited by long acquisition times - oft…

Near-perfect efficiency in X-ray phase microtomography
Dominik John, Gregor Breitenhuber, Sami Wirtensohn +8
X-ray microtomography at synchrotron sources is fundamentally limited by the high radiation dose applied to the samples, which restricts investigations to non-native tissue states…

Extending the field of view in modulation-based X-ray phase microtomography
Dominik John, Junan Chen, Christoph Gaßner +9
Recent advances in propagation-based phase-contrast imaging, such as hierarchical imaging, have enabled the visualization of internal structures in large biological specimens and m…
