An approximate method to model respiratory motion in a CAD human model subject to electromagnetic (or acoustic, thermal) finite-element analysis is suggested and described. Its concept implies using affine transformations, which are implemented in commercial FEM software packages, in the form of a parametric sweep. This method does not require multiple copies of the CAD model or multiple project files. It enables use of arbitrary sampling times and an automatic reposition of on-body and in-body devices. The method was applied to the platform-independent full-body electromagnetic computational model Visible Human Project® (VHP)-Female v. 3.1. Examples of scattering calculations and antenna modeling are provided.
提出并描述了一种在进行电磁（或声学、热学）有限元分析的CAD人体模型中对呼吸运动进行建模的近似方法。其概念是利用仿射变换，以参数扫描的形式在商业有限元软件包中实现。该方法不需要CAD模型的多个副本或多个项目文件。它允许使用任意采样时间，并能自动重新定位体表和体内装置。该方法应用于与平台无关的全身电磁计算模型可视人体计划®（VHP）-女性版本3.1。提供了散射计算和天线建模的示例。
