String-Averaging Expectation-Maximization for Maximum Likelihood Estimation in Emission Tomography

E. S. Helou, Y. Censor, T. -B. Chen +4

We study the maximum likelihood model in emission tomography and propose a new family of algorithms for its solution, called String-Averaging Expectation-Maximization (SAEM). In th…
