Performance of compressed sensing-based iterative reconstruction for single-photon emission computed tomography from undersampled projection data: a simulation study in( 123)I-N-omega-fluoropropyI-2 beta-carbomethoxy-3 beta-(4-iodophenyl)nortropane imaging

摘要

Objective The aim of this study was to investigate the efficacy of compressed sensing (CS)-based iterative reconstruction (CS-IR) from undersampled projection data in I- 123-N-omega-fluoropropyI-2 beta-carbomethoxy-3 beta-(4-iodophenyl)nortropane single-photon emission computed tomography (SPECT).
