摘　　要：目的:探讨周期运动过程中桡动脉横切面固靠性、轴心运动轨迹所形成角度与脉象流利度之间的关系。方法:应用新型中医取脉装置,同步采集25例具有不同流利度脉象的病人和20例平人关部脉的压力脉图、心电信号和桡动脉横截面动态超声图像,在MATLAB7.0.1软件对超声图像进行分析处理的基础上,观察周期运动中不同流利度脉象的桡动脉横切面图形固靠性和轴心运动轨迹角度的变化情况。结果:不同流利度脉象的桡动脉横切面轴心运动轨迹的帧间角度平均值、帧间固靠性变化率存在着一定的差异。结论:桡动脉横切面帧间固靠性变化率和轴心运动轨迹的帧间角度平均值可以作为初步判别流利度的一个参数。We studied the relationship between the solidity of transverse sections, centroid motion angles, and pulse fluency, during a cardiac cycle. 25 patients＇ and 20 healthy people＇s ECG, pressure sphygmograms, and ultrasound images of radial artery transverse sections were collected simultaneously using an advanced sphymograph. On the basis of image analysis using MATLAB 7.0.1, we observed and analyzed the solidity and angles of a cardiac cycle in pulse tracings with different fluencies. It is found that pulse tracings go with different fluencies, and there are significant differences in mean angles and solidity in the context of frames. We believe that the mean angles and solidity in the context of frames can be used to discriminate fluencies of pulse tracing.
