In this study, a 3T MRI database is used to create numerical children’s head models in order to study the variability of the specific absorption rate in the head of children at 7T using a transmit array head coil. These numerical models are integrated in a homemade multi-transmit RF coil model and then used to simulate SAR maps in the head using a finite difference time domain solver called GORF.
