Supervised Reconstruction for Silhouette Tomography

no code implementations11 Feb 2024 Evan Bell, Michael T. McCann, Marc Klasky

In this paper, we introduce silhouette tomography, a novel formulation of X-ray computed tomography that relies only on the geometry of the imaging system.

Machine Learning technique for isotopic determination of radioisotopes using HPGe $\mathrmγ$-ray spectra

no code implementations4 Jan 2023 Ajeeta Khatiwada, Marc Klasky, Marcie Lombardi, Jason Matheny, Arvind Mohan

$\mathrm{\gamma}$-ray spectroscopy is a quantitative, non-destructive technique that may be utilized for the identification and quantitative isotopic estimation of radionuclides.

Sparse-view Cone Beam CT Reconstruction using Data-consistent Supervised and Adversarial Learning from Scarce Training Data

no code implementations23 Jan 2022 Anish Lahiri, Marc Klasky, Jeffrey A. Fessler, Saiprasad Ravishankar

This work focuses on image reconstruction in such settings, i. e., when both the number of available CT projections and the training data is extremely limited.
