| 摘 要： | 通过分析彩超M型心动图及其边缘的特点,采用分段线性灰度变换的方法来抑制噪声,扩展图像的动态范围进行图像增强,使用基于线状模板搜索法的自动和准自动的边缘检测的方法,较准确地得到彩超M型心动图的边缘线.并由彩超M型心动图的边缘线进行微分处理得到的速度场、加速度场,为心血管疾病临床诊断提供重要的研究、诊断参数.由实验结果可以看出,该方法操作简便,使用效果好,实现了医学工程的扩展应用,对临床具有较好的应用价值.

| Abstract: | On analysis of new M-mode echocardiogram ultrasonic images and their edges,the study curbed noise through sub-linear gray-scale transformations,and enhanced images by expanding their dynamic range.Based on the use of linear search template,a semi-automatic detecting method of searching algorithm was proposed,which was proved quite effective in tracking the edges of echocardiogram.Carrying on the differential of dispersed position-time function,we obtained data of velocity field and acceleration field,provid... |
