Quantitative comparison of FBP, EM, and Bayesian reconstruction algorithms for the IndyPET scanner.

We quantitatively compare filtered backprojection (FBP), expectation-maximization (EM), and Bayesian reconstruction algorithms as applied to the IndyPET scanner-a dedicated research scanner which has been developed for small and intermediate field of view imaging applications. In contrast to previou...
