Real-time quasi-3D tomographic reconstruction
TL;DR: It is shown that by exploiting the mathematical properties of filtered backprojection-type methods, having access to real-time reconstructions of arbitrarily oriented slices becomes feasible and software for visualization and on-demand reconstruction of slices is presented.
Combined STEM-EDS tomography of nanowire structures

TL;DR: In this article, the 3D spatial resolution, the material contrast and the evolution of the noise are analyzed in the reconstructed volume of a combined scanning transmission electron microscopy (HAADF-STEM) and energy dispersive x-ray spectroscopy (EDS) tomography experiment.
Automated FDK-Filter Selection for Cone-Beam CT in Research Environments
TL;DR: This article presents a computationally efficient and automated method to compute an FDK-filter for a given measured projection dataset that is optimal with respect to an objectively defined quality criterion that is based on the difference between the measured projection data and the computed projections of the reconstructed volume.

TL;DR: The efficacy of the multigrid reconstruction principle is demonstrated using simulated data for quantitative assessment and experimental measurements from a clinically relevant use case scenario, and the expected artefacts from coarse discretization outside the region of interest become noticeable only for large differences in discretizations between subregions.
