block-sequential regularized expectation maximization(English)

• a Bayesian penalized-likelihood image reconstruction algorithm primarily used in nuclear medicine, such as PET and SPECT scans. It runs algorithms to full convergence while actively suppressing noise using a penalty term (beta), resulting in sharper images and higher lesion detectability
