Abstract
A new algorithm for SPECT reconstruction called ARTUR is proposed, which uses a Bayesian approach toward the maximum a posteriori estimator. It preserves discontinuities in the image by the use of regularization. We propose to compare it with one of the regularized version of the iterative method commonly employed in SPECT i.e. the maximum a posteriori expectation maximization one step late method, developed by Green.
