Numerical computation of radio-frequency (RF) fields in human body with implants is currently the only practical approach to obtain reliable estimation of the specific absorption rate (SAR) for safety assessment. Here we examine how detailed the model of a human body with a deep brain stimulation (DBS) implant needs to be to provide predictions of worst-case SAR scenarios for safety assessments.
