Using sparsity-based regularization to improve magnetic resonance image (MRI) reconstruction quality demands computation-intensive nonlinear optimization. In this paper, we develop an iterative algorithm based on the method of multipliers–augmented Lagrangian (AL) formalism–for reconstruction from sensitivity encoded data using sparsity-based regularization… CONTINUE READING
