中国人体惯性参数研究之三－女性人体（18～23岁）体段参数的CT法测定

THE DETERMINATION OF THE INERTIAL PARAMETERS OF THE SEGMENTAL FEMALE BODYS(18-23YEARS)WITH CT-METHOD

本文利用ＣＴ成像技术和电子计算机数字化图像处理系统的图像分析功能，对５０例女性青年大学生（１８～２３岁）进行了全身ＣＴ横断层扫描。将获得的断层图像依次输入ＩＭＧ２型数字化图像处理系统中。根据断层图像中各组织的灰度以及各种组织的比重值，对图像进行分析、测算和处理，综合计算出每例样本整体及其各体段的质量和质心位置等人体惯性参数。经验证和统计学检验，确立其准确性和可靠性，为建立中国人体惯性参数模型提供了重要数据。也为体育项目的科学训练提供了可靠依据。

Taking advantage of the technique of Computerized Tomography(CT)and the functions of the Digital Image Processing System(DIP)in this paper,50 young female medical students were scanned by CT from head to foot.The achieving images were imported into DIP and were processed by it.According to the dark degree of the tissues in the image and the determined density of the various tissues, the weight and mass center of the segments and the total body of every individual was counted with the DIP.Going through the analysis,examination,and statistics,the accuracy and reliability of the data was defined.Thus,a dependable data was provided for building up the model of the inertialparameters of the Chinese human body and for Sporting movement.
