Abstract

A hybrid method is presented which allows the acceleration of parallel MR imaging through combining the ideas of compressed sensing with inversion of the imaging matrix. A novel data reordering is employed to enhance the sparsity inherent in the image transform. Simulation results with actual head scan data are presented.
