【摘要】 针对心脏截面图像上内腔边缘形状起伏较大的特点 ,利用一种基本思想称为径向半径搜寻的方法 ,获取内腔边缘的包络曲线 .首先介绍的径向半径搜寻方法较以往的方法提高了对不光滑边缘轮廓提取的精确程度 ,然后对该方法进行改进 ,从而使心脏内腔边缘曲线的提取方法在鲁棒性、准确性方面较以往的方法有较大的提高 ,并具有普遍性更多还原

【Abstract】 Corresponding to the fluctuant characteristic of cardiac lumen borders on an echocardiographic slice image, a method called radial search technique to estimate the curve of border contour is proposed, which can improve the accuracy of estimation for unsmoothed borders, and then based on this technique an even better method which obviously increases the robusticity and accuracy further is also presented.更多还原
