MRI multi-row array coils can offer increased flexibility to control and tailor the RF field distribution through RF Shimming. The performance of various multi-row configurations of parallel-transmit (pTx) RF coil array for brain imaging at 3T is investigated using electromagnetic field simulations with digital human computational model for overlapping and non-overlapping loop coil elements in 16- to 24-channel single, double, triple-row arrays. We found that triple-row coil arrays improve the transmit field homogeneity in the entire volume of the head. The double-row coil array offers the best SAR efficiency among other investigated coils.
