For each of the tasks, we demonstrate the reconstructed images for two typical cases with their corresponding error maps compared to the ground-truth (GT) images. Ordered subset expectation-maximization (OSEM), filtered back projection (FBP), and zero filling (ZF) are traditional methods for PET, CT, MAR, and MRI reconstruction.
