摘要 温升效应是电磁辐射的一个重要生物效应,引起眼球的温升效应最明显。针对目前无法对人类眼球温升进行无损活体测量的难题,提出了基于时域有限差分算法和生物热方程的数值仿真方法。利用EMPro电磁仿真软件对人类头部建模并对眼球吸收的电磁辐射能量进行仿真;再利用Matlab PDE工具箱对眼球建模并对眼球温升进行仿真。研究发现:眼球内10g平均SAR峰值和眼球最大温升的比值R约为0.165。R值的意义在于可根据眼球吸收的电磁辐射能量对眼球最大温升进行估算,为研究电子磁辐射对人眼损伤提供依据。 An important biological effect of electromagnetic radiation is temperature increase, especially in eyes. For difficulties of non-destructive live measurement of temperature increase in eyes, numerical simulation based on the finite difference time-domain method and bio-heat equation was proposed. Human head was modeled and electro-magnetic radiation energy absorbed by eyes was simulated by using EMPro. Human eyes were modeled and tempera- ture increase was calculated with Matlab PDE toolbox. The results indicate that the ratio R of maximum average 10g SAR and temperature increase in eyes, is about 0. 165. Thus the maximum temperature increase in eyes can be esti-mated according to the electromagnetic radiation energy absorbed by eyes.
