Superiorization of Preconditioned Conjugate Gradient Algorithms for Tomographic Image Reconstruction

Elias S. Helou, Gabor T. Herman, Chuan Lin +1

Properties of Superiorized Preconditioned Conjugate Gradient (SupPCG) algorithms in image reconstruction from projections are examined. Least squares (LS) is usually chosen for mea…
