Factorized Projection-Domain Spatio-Temporal Regularization for Dynamic Tomography

Berk Iskender, Marc Louis Klasky, Brian M. Patterson, Yoram Bresler

ICASSP 2023accepted

Dynamic tomography is an ill-posed inverse problem where the object evolves during the sequential acquisition of projections. The goal is to reconstruct the object for each time instant. However, performing a direct reconstruction using this inconsistent set of projections is impossible. In this pap…

RED-PSM: Regularization by Denoising of Partially Separable Models for Dynamic Imaging

Berk Iskender, Marc L. Klasky, Yoram Bresler

ICCV 2023poster

Dynamic imaging involves the recovery of a time-varying 2D or 3D object at each time instant using its undersampled measurements. In particular, in dynamic tomography, only a single projection at a single view angle may be available at a time, making the problem severely ill-posed. In this work, we…
