Stopping criterion for the iterative EM-MLE image reconstruction for PET

TL;DR: A stopping criterion for the EM-MLE algorithm for PET is proposed, based on the properties of the multiplicative correction factors (Delta) x applied to the image vector after each iteration, which has been applied to reconstructions from real data from the CTI-831 NeuroPET scanner.

TL;DR: Weerts et al. as mentioned in this paper corrected the legend of the y-axis of Fig 4 to read σ ( pp → LQLQ ) as shown in the corrected Fig 4 attached, rather than σ × BR.

Studying the properties of the updating coefficients in the OSEM algorithm for iterative image reconstruction in PET

TL;DR: The experiments showed that the statistical properties of these coefficients can be correlated with the quality of the reconstructed images as a function of the activity distribution in the source and the number of subsets used.
