B1 Shimming Performance Versus Channel/Mode Count

Paul R. Harvey¹, Cecilia Possanzini¹, Jan Simons¹

This study reports on simulations of abdominal B1 shimming performance, using a multi-element volume body coil, as a function of transmit channel/mode count and available RF power. Results indicate that increasing channel/mode count provides limited improvement in uniformity at the cost of higher power.
