MaxSAR1g around DBS electrodes in the homogeneous body model during RF exposure at 64 MHz and 127 MHz, when the conductivity of the tissue was changed from 0.01 s m−1 to 1 s m−1. The variation of MaxSAR1g due to changes in grey matter and white matter conductivities in the heterogeneous body model are also given for comparison. For each simulation, the input power of the coil was adjusted to generate the global head SAR of 3.2 W kg−1.
