To evaluate safety of a 500 MHz inductive birdcage resonator for human brain MRI at 11.7 T, we compared phantom SAR measurements with predictions based on simulations. On a head-shaped phantom with realistic permittivity and conductivity, good correspondence was achieved in heating distributions when irradiating the phantom with 85 W RF power. The ability to predict SAR at 500MHz with simulation is critical step towards in-vivo MRI at 11.7 T.
