随着计算机性能的进步，整个人体的高分辨率体素模型在电磁波数值剂量测定中的使用变得更加频繁。利用磁共振成像，我们为日本成年男性和女性的平均身高和体重开发了逼真的高分辨率全身体素模型。开发的模型由每边 2 毫米的立方体素组成；这些模型被分为 51 个解剖区域。成年女性模型是世界上第一个此类模型，也是第一个亚洲体素模型（代表日本人的平均水平），能够在高达 3 GHz 的高频下对电磁剂量测量进行数值评估。在本文中，我们还将描述使用有限差分时域方法计算的 VHF/UHF 频段开发模型的基本 SAR 特性。
With advances in computer performance, the use of high-resolution voxel models of the entire human body has become more frequent in numerical dosimetries of electromagnetic waves. Using magnetic resonance imaging, we have developed realistic high-resolution whole-body voxel models for Japanese adult males and females of average height and weight. The developed models consist of cubic voxels of 2 mm on each side; the models are segmented into 51 anatomic regions. The adult female model is the first of its kind in the world and both are the first Asian voxel models (representing average Japanese) that enable numerical evaluation of electromagnetic dosimetry at high frequencies of up to 3 GHz. In this paper, we will also describe the basic SAR characteristics of the developed models for the VHF/UHF bands, calculated using the finite-difference time-domain method.
