Paper Abstract

Green’s one-step-late (OSL) algorithm is a popular image reconstruction algorithm in emission data tomography, in spite of its convergence issues. One drawback of Green’s algorithm is that the algorithm exhibits non-stationary regularization when the algorithm’s projector and backprojector model the attenuation effects in single photon emission computed tomography (SPECT). This paper suggests a remedy to improve Green’s OSL algorithm so that stationary regularization can be obtained.
