An overview of fast convergent ordered-subsets reconstruction methods for emission tomography based on the incremental EM algorithm
Statistical reconstruction has become popular in emission computed tomography but suffers slow convergence (to the MAP or ML solution). Methods proposed to address this problem include the fast but non-convergent OSEM and the convergent RAMLA [1] for the ML case, and the convergent BSREM [2], relaxe...
