B超心脏序列图象左室短轴轮廓曲线的动态跟踪

介绍了一种动态跟踪心脏序列图象轮廓的新方法 .先人工找出第一帧图象的轮廓 ,再根据序列图象相邻帧之间反映心脏肌体的位置和灰度信息上的相关性、心脏左室短轴的运动趋势等基本特征制定基本策略 ,结合曲线拟合技术 ,用互相关法自动跟踪后面序列图象的轮廓

Tracking of the left ventricle vrachyaxis contour curve in ultrasound B-scan sequence images based on correlation function

This paper introduces a new method of tracking the left ventricle in echocardiographic sequence images. The feature points of image boundary at the first frame will be found manually. Then these points can be formed to the boundary by the technique of curve fitting. Owing to the fact that the position and gray scale between two sequence frames are correlative, the object boundary can be tracked automatically based on correlation function.
