RF induced heating is an important safety concern as the number of patients implanted with medical devices increases and the use of 3T MRI becomes more prevalent. We hypothesize that the combination of Magnetic Resonance Thermometry (MRT) and multiphysics simulation would provide a more accurate assessment of MR safety than current in vitro test methods, and could ultimately be used to evaluate RF induced heating of devices in vivo. The purpose of this work is to evaluate the feasibility of this approach by comparing temperature probe measurements with MRT and multiphysics simulation of RF induced heating near a metallic device.
