Penalized Likelihood PET Image Reconstruction using Patch-based Edge-preserving Regularization
Iterative image reconstruction for positron emission tomography (PET) can improve image quality by using spatial regularization that penalizes image intensity difference between neighboring pixels. The most commonly used quadratic penalty often over-smoothes edges and fine features in reconstructed...
