Abstract

Magnetic resonance (MR) image reconstruction is to get a practicable gray-scale image from few frequency domain coefficients. In this paper, different reweighted minimization models for MR image reconstruction are studied, and a novel model named reweighted wavelet+TV minimization model is proposed. By using split Bregman method, an iteration minimization algorithm for solving this new model is obtained, and its convergence is established. Numerical simulations show that the proposed model and its algorithm are feasible and highly efficient.
