Isotopic gamma lines for identification of shielding materials
Oleg Korobkin, Marc L. Klasky, Ajeeta Khatiwada +1
Identifying the constituting materials of concealed objects is crucial in a wide range of sectors, such as medical imaging, geophysics, nonproliferation, national security investig…
Score-based Diffusion Models for Bayesian Image Reconstruction
Michael T. McCann, Hyungjin Chung, Jong Chul Ye +1
This paper explores the use of score-based diffusion models for Bayesian image reconstruction. Diffusion models are an efficient tool for generative modeling. Diffusion models can…
RED-PSM: Regularization by Denoising of Factorized Low Rank Models for Dynamic Imaging
Berk Iskender, Marc L. Klasky, Yoram Bresler
Dynamic imaging addresses the recovery of a time-varying 2D or 3D object at each time instant using its undersampled measurements. In particular, in the case of dynamic tomography,…
Material Identification From Radiographs Without Energy Resolution
Michael T. McCann, Elena Guardincerri, Samuel M. Gonzales +3
We propose a method for performing material identification from radiographs without energy-resolved measurements. Material identification has a wide variety of applications, includ…
Machine Learning technique for isotopic determination of radioisotopes using HPGe -ray spectra
Ajeeta Khatiwada, Marc Klasky, Marcie Lombardi +2
-ray spectroscopy is a quantitative, non-destructive technique that may be utilized for the identification and quantitative isotopic estimation of radionuclides. Traditio…
