Using finite difference time domain simulations, the effect of different relative permittivity of the dielectric located between the body and volume array at 7T is examined. Additionally, RF shielding within the volume array is studied to predict B1 transmit patterns in the body. These are combined to improve B1 efficiency and homogeneity at 7T.
