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 approximately 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.
本文介绍了在人体解剖学逼真的体素模型中对全身平均比吸收率（SAR）进行的时域有限差分（FDTD）计算。该模型NORMAN由约900万个体素组成，在成人体模中尺寸为2毫米，分为37种组织类型。给出了成人体模以及按比例缩放的10岁、5岁和1岁模型在1兆赫兹至1吉赫兹平面波照射下，接地和在空气中孤立时的SAR值。还给出了对应全身平均SAR为0.4瓦每千克的外部电场值。
