The left ventricle vrachyaxis contour—tracking of sectional echocardiography image based on improved active contour model

提出了一种序列超声心动图左室短轴轮廓跟踪方法.运用改进式主动轮廓模型算法并结合帧间图像配准原则逐帧进行轮廓提取,从而实现序列超声心动图左室短轴轮廓跟踪.该方法的突出特点是在复杂的心脏运动条件下解决左室短轴运动的序列图像轮廓跟踪问题.从实验结果可以看出,该方法能够比较准确地跟踪序列超声心动图左室短轴轮廓.

The paper describes a method of the left ventricle vrachyaxis contour-tracking in sectional echocardiography image. Describes the contour using the improved active contour model which combines the principle of image matching between frames, accordingly realizes the left ventricle vrachyaxis contour-tracking of echocardiography image. It can settle the problem of the active left ventricle vrachyaxis on the condition of complex heart movement. The results show that the method can track the left ventricle vrachyaxis contour exactly.
