Simulation-driven design and optimization of RF coil arrays for MRI

Abstract

We provide recommendations for simulation-driven design and work-flow for magnetic resonance imaging RF transmit-coil arrays. To enable final decisions on array construction, accurate knowledge is needed of how the array transmit and safety measures depend on the array geometry, RF component losses, and the tuning and excitation conditions. If strong evidence is provided that array safety excitation efficiency is insensitive to tuning condition, head geometry and head position, the safety margin can be reduced, allowing shorter scan times.
