Synopsis: In this work, we present a new and an elaborate dual-optimization method that maintains RF-coil RF characteristics and simultaneously reduces low frequency magnetic field distortions due to eddy currents. The optimization is guided by full wave electromagnetic simulation combined with eddy current simulation. The designs were successfully tested on a 7T human scanner using phantoms and 4 in-vivo subjects.
