Abstract
A method for target-dependent, sparsity-enforced selection for choosing a substantially optimal connection of radiofrequency ('RF') transmitters to the elements of the RF coil array is provided. In particular, a method is provided that selects the linear combinations of the 'N' spatial mode profiles of a transmission RF coil array, such that the k-space trajectory and pulse duration acceleration capabilities of the array are advantageously utilized. A sparsity-enforcement method that determines a subset of the available spatial modes for a parallel transmission RF coil array is employed to this end. In this manner, the utilization of the encoding power of a highly-parallel N-mode coil array in a system with only “P” available excitation channels is enabled.
