Accurate 2D Reconstruction for PET Scanners based on the Analytical White Image Model
In this paper, we provide a precise mathematical model of crystal-to-crystal response which is used to generate the white image - a necessary compensation model needed to overcome the physical limitations of the PET scanner.
Accurate PET Reconstruction from Reduced Set of Measurements based on GMM
A vast majority of PET imaging methods are based on reconstruction model that is defined by values on some pixel/voxel grid.
Estimating Uncertainty in PET Image Reconstruction via Deep Posterior Sampling
The method is based on training a conditional generative adversarial network whose generator approximates sampling from the posterior in Bayesian inversion.
