Penalized PET/CT Reconstruction Algorithms with Automatic Realignment for Anatomical Priors
Yu-Jung Tsai, Alexandre Bousse, Simon Arridge +3
Two algorithms for solving misalignment issues in penalized PET/CT reconstruction using anatomical priors are proposed. Both approaches are based on a recently published joint moti…
