The use of transmit arrays for transmit SENSE, B1 shimming, and phase compensation of SEA coils has made large scale parallel transmit systems desirable. Our group has developed a system capable performing static modulation on 64 channels, or fast modulation on 8 channels with an output power of 100W per channel. The large channel count drove design to produce a modular system that is easier to test, troubleshoot, and construct. Consideration was also given to thermal and space issues that could arise from such a large system.
