In this study, RF heating of an EEG on a 29-month-old whole-body voxel model in a 3T MRI was studied with numerical simulation using Sim4Life. 128-channel EEG leads and electrodes were drawn on the head of the 29-month-old voxel model, and the position of the EEG electrodes was estimated from the 3D scan of the EEG net. The 10gSAR_max and the SAR_head were assessed in the model with and without the EEG net in birdcage transmit body coil at 3T. In both cases, estimated results of SAR were well-below the RF safety limit in the international standard.
