List-Mode Likelihood: EM Algorithm and Image Quality Estimation Demonstrated on 2-D PET
Using a theory of list-mode maximum-likelihood (ML) source reconstruction presented recently by Barrett et al. [1], this paper formulates a corresponding expectation-maximization (EM) algorithm, as well as a method for estimating noise properties at the ML estimate. List-mode ML is of interest in ca...
