This abstract presents a novel technique to determine the suitable tissue simulating medium (TSM) conductivity for MRI lead electrode RF heating transfer function (TF) determination. The proposed method utilizes validated numerical lead model in conjunction with tissue models extracted along lead trajectories in anatomical models to produce in-vivo transfer function models. When combined with in-vivo incident electric fields, the power deposition or temperature rise predicted by the in-vitro and in-vivo TFs can be compared to assess the suitability and conservativeness of the selected TSM conductivity.
