Maximum temperature increases in the head and brain for SAR averaging schemes prescribed in safety guidelines

This paper presents maximum temperature increase in the head and brain with peak SAR calculated by different averaging schemes. For our computational investigations, it is found that maximum temperature increases in the head are well correlated with peak spatial-average SARs. However, the slope correlating them is largely dependent on the averaging scheme. Additionally, no clear difference is observed in the slope obtained using two head models. Possible maximum temperature increase in the brain for the SAR values is also quantified.
