微波热疗温度场仿真中SAR分布影响因素的研究
Research on Inlfuence Factors of SAR Distribution in Temperature Field Simulation of Microwave Hyperthermia
摘要
Abstract
In order to improve the accuracy of temperature ifeld 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 iftting and introduction of optimum iftting method of SAR distribution. The results of massive calculation and simulation comparison showed that the weighted least squares iftting 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 iftting were choosed as 60 s、70 s…110 s.关键词
