本文提出了人体解剖学真实体素模型中全身平均 SAR 的时域有限差分 (FDTD) 计算。该模型 NORMAN 由成人体模中类似 900 万个尺寸为 2 毫米的体素组成，分为 37 种组织类型。 SAR 值针对成人体模以及 10、5 和 1 岁的比例模型，接地并在空气中隔离，频率为 1 MHz 至 1 GHz，用于平面波暴露。还给出了与 0.4 W kg(-1) 全身平均 SAR 相对应的外部电场值。
This paper presents finite-difference time-domain (FDTD) calculations of the whole-body averaged SAR in an anatomically realistic voxel model of the human body. This model, NORMAN, consists of similar to 9 million voxels, of 2 mm dimension in the adult phantom, segmented into 37 tissue types. SAR values are presented for an adult phantom and for scaled 10, 5 and 1 year old models, grounded and isolated in air from 1 MHz to 1 GHz for plane wave exposure. External electric field values corresponding to a whole-body averaged SAR of 0.4 W kg(-1) are also presented.
