Transmit Strategies for Body Imaging at 3T - Comparing Multitransmit and Dielectric Shimming

Wyger M. Brink¹, Andrew Webb¹

High permittivity pads are shown to improve the B1 homogeneity to a level similar to that of an eight-channel system, however without the penalty of reducing the transmit efficiency. The best transmit setup for 3T body imaging is shown to be the two-channel system with high permittivity pads.
