Multitransmit technology has the potential to overcome local SAR limitations and make flip angles more uniform. In this study, color coded SNR maps and B1 frequency shift maps are generated to compare the multitransmit technology to traditional, single channel technology. It is shown that the the local SAR is reduced substantially and image homogeneity is improved with multitransmit.
