Efficient fully 3D list-mode TOF PET image reconstruction using a factorized system matrix with an image domain resolution model
A factorized system matrix utilizing an image domain resolution model is attractive in fully 3D TOF PET image reconstruction using list-mode data. In this paper, we study a factored model based on sparse matrix factorization that is comprised primarily of a simplified geometrical projection matrix a...
