Joint Reconstruction of Multi-channel, Spectral CT Data via Constrained Total Nuclear Variation Minimization
David Rigie, Patrick La Riviere
We explore the use of the recently proposed "total nuclear variation" (TNV) as a regularizer for reconstructing multi-channel, spectral CT images. This convex penalty is a natural…

X-ray tomography system to investigate granular materials during mechanical loading
Athanasios G Athanassiadis, Patrick J. La Rivière, Emil Sidky +3
We integrate a small and portable medical x-ray device with mechanical testing equipment to enable in-situ, non-invasive measurements of a granular material's response to mechanica…
