摘要

将人体组织中SAR峰值(比吸收率)的位置和分布与SAR引起的温度升高进行了比较。温度变化包括血液灌注的冷却效应，可能是暴露引起的组织损伤的更好指标。本文描述了一种基于体素的几何文件的有限差分计算温升的技术。给出了一个由人头辐射的简化蜂窝电话的实例。

FDTD comparison of SAR and temperature rise in human tissue

A comparison is made between the peak SAR (specific absorption rate) location and distribution in human tissue with the resulting temperature rise caused by the SAR. The temperature change includes cooling effects from the perfusion of blood and may be a better indicator of tissue damage caused by exposure. This paper describes a technique for computing the temperature rise in a finite difference approach for voxel-based geometry files. An example is presented for a simplified cellular telephone radiating by a human head.
