Previously, we proposed an algorithm, ECOSEM-ML (Enhanced Complete-Data Ordered Subsets Expectation-Maximization), for fast maximum likelihood (ML) reconstruction in emission tomography (ET). Here we extend the ECOSEM algorithm to an maximum a posteriori (MAP) reconstruction by including a smoothing separable surrogate prior, and this new MAP algorithm is… CONTINUE READING
