【摘要】：汽车碰撞事故中,肋骨密质骨厚度分布对肋骨骨折特性有显著影响,其形态学特征与人体参数等因素密切相关。该文定量描述了肋骨密质骨厚度分布,并分析了年龄、性别、身高和身高质量指数(BMI)等人体参数的影响。以60例中国人医学计算机断层扫描(CT)图像数据为样本,采用基于CT值分布特征的肋骨密质骨厚度测量方法,对每例CT图像的左侧12根肋骨进行了分布式测量。应用统计学方法,研究了位置和人体参数对肋骨密质骨厚度的影响。结果表明:肋骨序号、肋骨截面序号、测量点位置等位置参数和性别、身高、BMI等人体参数均对肋骨密质骨厚度具有显著影响。该研究所确立的肋骨密质骨厚度分布模型可应用于开发参数化人体有限元模型,有助于定量研究人体参数对肋骨骨折的影响。
[Abstract]:In automobile crash, the thickness distribution of rib dense bone has a significant effect on the characteristics of rib fracture, and its morphological characteristics are closely related to human parameters and other factors. The distribution of rib dense bone thickness was quantitatively described, and the influence of age, sex, height and height and mass index (BMI) on human body parameters were analyzed. Based on the CT image data of 60 Chinese patients, a method of measuring the thickness of rib dense bone based on the distribution of CT values was used to measure 12 ribs on the left side of each CT image. The influence of position and human parameters on the thickness of rib dense bone was studied by statistical method. The results showed that the body parameters, such as rib serial number, rib cross-section serial number, position of measurement point, sex, height and BMI, all had significant effects on the thickness of rib dense bone. The model of rib dense bone thickness distribution can be used to develop parameterized finite element model of human body, which is helpful to quantitatively study the influence of human parameters on rib fracture.
