A common method used for iterative reconstruction in emission tomography is the maximum likelihood expectation maximization (MLEM) algorithm [6]. This method seeks to reconstruct the object “most likely” in a statistical sense to have ...

In every iteration the algorithm checks the current estimate and improves it based on that evaluation. A key feature of iterative ... In fact, this is the main difference between MLEM and other iterative reconstruction algorithms.

The MLEM algorithm converges slowly, requiring many more iterations than iterative FBP algorithms; however, the slowly converging characteristics of this algorithm yield greater control over image noise.19,29 The point of convergence of ...
