Synopsis: An array-compressed parallel transmit pulse design concept is proposed to enable many-coil transmit arrays to be optimally driven by a small number of RF amplifiers/channels. It is demonstrated in three pulse design applications that by integrating coil compression into parallel transmit pulse design, more accurate pulses can be designed than with approaches that do not consider the spatial encoding demands of the pulse design problem when computing coil array combination weights.
