The
potential to accelerate the B1+ mapping measurement by means of
compressed sensing (CS) was investigated. Joint sparsity constraint
accounting for the common sparsity support in different TX channels, and
higher dimensional undersampling space,
also including the coil dimension, allow for considerable acceleration
even for the low resolution data acquired in B1+ mapping. The
basic feasibility of the proposed method is evaluated on simulations and in
vivo data from a 3T 8-channel parallel transmit system.
