Safety assessment for multi-channel RF transmission systems requires the analysis of specific absorption rate (SAR) in a subject-specific manner. Since SAR depends on individual subject anatomy and on the multi-channel excitation scheme, traditional approaches that rely on generic subject models and worst-case scenario evaluations may result in excessive overestimations. With the advancement of computational electromagnetics techniques, fast full-wave simulations of actual subject models have been proposed. In this study, we demonstrate that high simulation accuracy can be achieved with these techniques in real time.
