本文的目的是重建上气道几何模型的混合网格从临床使用的计算机断层扫描（CT）数据集，以了解阻塞性睡眠呼吸暂停综合征（OSAS）患者的术前和术后上气道系统的动力学和行为的粘性计算流体动力学（CFD）模拟。OSAS病例研究的选择标准进行了讨论，因为两个合理的术前和术后上气道模型的CFD模拟可能不会创建为每个情况下，没有一个特殊的协议进行CT扫描。几何提取和操作方法与必须克服的技术障碍一起提出，以便它们可以与计算模拟软件一起沿着用作日常临床评价工具。本文介绍了8例病例，每例病例均包括术前和术后配置。文中给出了两种情况下的计算模拟结果。
The objective of this paper is the reconstruction of upper airway geometric models as hybrid meshes from clinically used Computed Tomography (CT) data sets in order to understand the dynamics and behaviors of the pre- and postoperative upper airway systems of Obstructive Sleep Apnea Syndrome (OSAS) patients by viscous Computational Fluid Dynamics (CFD) simulations. The selection criteria for OSAS cases studied are discussed because two reasonable pre- and postoperative upper airway models for CFD simulations may not be created for every case without a special protocol for CT scanning. The geometry extraction and manipulation methods are presented with technical barriers that must be overcome so that they can be used along with computational simulation software as a daily clinical evaluation tool. Eight cases are presented in this paper, and each case consists of pre- and postoperative configurations. The results of computational simulations of two cases are included in this paper as demonstration.
