In this paper, a full-wave simulation-based method is proposed to determine the optimal tissue-simulating medium for magnetic resonance imaging radio-frequency safety assessment for patients with active implantable medical devices (AIMDs). Compared to the standard medium, the proposed tissue-simulating medium is optimized for each AIMD lead path in human bodies. The reciprocity-based transfer function model is used as a criterion for optimizing the medium parameters. Numerical investigations and validations are performed for a neurostimulator to demonstrate the method.
