| Abstract(in English) | Specific absorption rate (SAR) is used as a metric for human protection from radio-frequency exposure although biological effect due to radio-frequency absorption is caused by the temperature elevation. The temperature elevation for microwave exposure has not been investigated sufficiently in the frequency region above 3 GHz. According to previous studies, one of the most dominant factors affecting the temperature elevation in the biological tissue was suggested to be the blood perfusion rate in tissue. The in-vivo measurement of blood perfusion rate in the head, however, has not been reported until now. In the present study, we investigated temperature elevation in the head due to dipole antenna from 1 to 12 GHz. Measured blood flow in the head was incorporated in the computation to discuss the individual variability of temperature elevation. The variability of the maximum temperature elevation in the head due to the blood perfusion rate was ±30% in anatomically based head models. |
