Relaxed ordered subset preconditioned alternating projection algorithm for PET reconstruction with automated penalty weight selection
PURPOSE: Performance of the preconditioned alternating projection algorithm (PAPA) using relaxed ordered subsets (ROS) with a non‐smooth penalty function was investigated in positron emission tomography (PET). A higher order total variation (HOTV) regularizer was applied and a method for unsupervise...
