Anatomically accurate and numerically efficient computational phantoms of humans are essential to characterizing the response of a body to a variety of electromagnetic, acoustic and other types of external stimuli. In conjunction with advances in numerical simulation techniques and computational hardware, these computational phantoms enable exploration of innovative and exciting applications, from medical diagnostic techniques and therapeutic treatments to new ways of on- and in-body communications. However, in order to provide realistic estimates through simulation, the model must represent the subject as closely as possible, necessitating that all relevant anatomical features are captured. If this is not accomplished, the model will misrepresent the true physical environment, and critical information will not be captured during the simulation. This work presents a model of a male subject based on the Visible Human Project dataset. Each component of the model is constructed of triangular surface elements, making it compatible with CAD packages and facilitating its use in simulations based on major numerical methodologies. A description of the model, the procedure used for its construction and a baseline simulation are presented together with future integration and augmentation ideas.
人体解剖结构精确且数值计算高效的计算体模,对于刻画人体对各种电磁、声学及其他类型外部刺激的反应至关重要。结合数值模拟技术和计算硬件的进步,这些计算体模能够探索创新且令人兴奋的应用,从医学诊断技术和治疗方法到体内外通信的新方式。然而,为了通过模拟提供现实的估计,模型必须尽可能逼真地呈现对象,这就需要捕捉所有相关的解剖特征。如果做不到这一点,模型就会错误地呈现真实的物理环境,并且在模拟过程中无法捕捉到关键信息。这项工作基于可视人项目数据集提出了一个男性对象的模型。模型的每个组件均由三角形表面元素构成,使其与CAD软件包兼容,并便于在基于主要数值方法的模拟中使用。本文介绍了模型描述、构建模型所使用的过程以及基线模拟,同时还提出了未来集成和扩充的思路。
