In this study, an 8-channel (8ch) loop and a 2-channel (2ch) birdcage in 5T frequency are built and compared. Basic electrical characteristics, engineering issues in implementation, transmitting efficiency, perturbation sensitivity, B1+ uniformity and local SAR are compared between these two coils. Measurement result of the B1+ distribution in torso region with these coils are obtained from a whole body 5T MRI scanner.
