Study of the Effect and Simulation of Water Vaporization in Tissues on Temperature Distribution in Microwave Hyperthermia

In order to improve the accur acy of near-field forecasting temperature during microwave hyperthermia,this paper analyses the rising curve of the temperature in near-field,and studies the effect of water vaporization.The enthalpy of liver issues and high-temperature SAR are calculated and introduced to simulation process.The results show that the accuracy of near-field temperature in simulation is improved.
