ADMM-EM Method for L (1)-Norm Regularized Weighted Least Squares PET Reconstruction
The L (1)-norm regularization is usually used in positron emission tomography (PET) reconstruction to suppress noise artifacts while preserving edges. The alternating direction method of multipliers (ADMM) is proven to be effective for solving this problem. It sequentially updates the additional var...
