Fast reconstruction of Bayesian iterative approximation in passive gamma-ray tomography

Median root prior expectation maximization (MRPEM) algorithm that belongs to the Bayesian iterative approximation is used in passive gamma emission tomography (GET) to reconstruct passive gamma emitter distribution. The algorithm converges slowly and may involve iterations of 50-200. Fast processing...
