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.
