Abstract:In order to improve the accuracy of temperature field simulation of microwave hyperthermia, this study analyzed the influence factors of SAR distribution in terms of quantitative calculation of temperature error, determination of effective time points of SAR fitting and introduction of optimum fitting method of SAR distribution. The results of massive calculation and simulation comparison showed that the weighted least squares fitting method would be more stable and effective than the traditional method when the temperature error was controlled within 3.5 ℃ and the time points of SAR fitting were choosed as 60 s、70 s…110 s.
