Advanced Brain Tissue Imaging with Data-Consistent Diffusion Priors in Laminographic X-Ray Nanoimaging
Wenxuan Fang, Abraham L. Levitan, Ana Diaz +10
Nanoscale imaging of mammalian brains is critical for connectomics. X-ray laminography enables high-throughput imaging of extended, plate-like biological specimens. However, the ti…
Free-form diamond refractive optics enable efficient high-energy X-ray nano-imaging
Aknur Karabay, Xianbo Shi, Frank Seiboth +4
Full-field transmission X-ray microscopy (TXM) enables nondestructive three-dimensional imaging of thick and strongly absorbing materials with high spatial resolution. Such capabil…
X-ray linear dichroic orientation tomography: reconstruction of nanoscale three-dimensional orientation fields
Andreas Apseros, Valerio Scagnoli, Manuel Guizar-Sicairos +3
Properties in crystalline and ordered materials tend to be anisotropic, with their orientation affecting the macroscopic behavior and functionality of materials. The ability to ima…
Diffusion Active Learning: Towards Data-Driven Experimental Design in Computed Tomography
Luis Barba, Johannes Kirschner, Tomas Aidukas +2
We introduce Diffusion Active Learning, a novel approach that combines generative diffusion modeling with data-driven sequential experimental design to adaptively acquire data for…
Single-shot X-ray ptychography as a structured illumination method
Abraham Levitan, Klaus Wakonig, Zirui Gao +4
Single-shot ptychography is a quantitative phase imaging method wherein overlapping beams of light arranged in a grid pattern simultaneously illuminate a sample, allowing a full pt…
Fast Small-Angle X-ray Scattering Tensor Tomography: An Outlook into Future Applications in Life Sciences
Christian Appel, Margaux Schmeltz, Irene Rodriguez-Fernandez +18
Small Angle-X-ray Scattering Tensor Tomography (SAS-TT) is a relatively new, but powerful technique for studying the multiscale architecture of hierarchical structures, which is of…
X-ray Linear Dichroic Tomography of Crystallographic and Topological Defects
Andreas Apseros, Valerio Scagnoli, Mirko Holler +6
The functionality of materials is determined by their composition and microstructure, that is, the distribution and orientation of crystalline grains, grain boundaries and the defe…
Hard X-ray grazing incidence ptychography: Large field-of-view nanostructure imaging with ultra-high surface sensitivity
