| 摘 要： | 目的建立OSAHS（阻塞性睡眠呼吸暂停低通气综合征）患者的上气道及比邻结构三维有限元模型,为OSAHS的生物力学分析打下基础。方法对OSAHS患者上气道行薄层CT扫描,获得OSAHS患者上气道DICOM格式的图像信息,采用Mimics三维建模软件和Ansys三维有限元分析软件建立上气道及比邻结构的三维有限元模型。结果建立了国内首例OSAHS患者上气道及比邻结构的三维有限元模型,共得到172062个单元,32958个节点,既能精确显示其三维空间结构和形态,又能模拟治疗睡眠呼吸暂停低通气综合征评价疗效。结论建立准确、可作灵活模拟操作的OSAHS患者上气道及其比邻结构三维有限元模型,为进行临床治疗OSAHS及其上气道生物力学分析打下良好的基础。 |

| Abstract: | Objective To establish a three-dimensional finite element model of the upper airway in patients with obstructive sleep apnea hypopnea syndrome.Methods The section images of an OSAHS patient's upper airway acquired by thin-section CT scanning and digital image processing were utilized to construct a three-dimensional finite element model by Mimics and Ansys software.Results The three-dimensional finite element model was constructed which including 172062 elements and 32958 nodes,with the upper airway and vic... |
