FDTD computation of temperature elevation in the head model due to dipole antenna with measured blood flow rate

摘要

The present study investigates the microwave-induced temperature elevation in a Japanese human head model named TARO, for frequencies ranging from 1 to 12 GHz. A half-wave dipole antenna is considered as a wave source at respective frequencies. Bioheat equation is solved to compute the temperature elevation caused by microwave absorption. Measured blood flow rate in the head was incorporated in the computation to discuss the individual variability of temperature elevation. Computational results show the variability of the maximum temperature elevation in the head due to the blood flow rate was ±30%.
