Abstract: Methods and systems for segmentation in echocardiography are provided. One method includes obtaining echocardiographic images and defining a search space within the echocardiographic images using a pair of one-dimensional (1D) profiles. The method also includes using an energy based function constrained by non-local temporal priors within the defined search space to automatically segment a contour of a cardiac structure with the 1D profiles.

Abstract translation: 提供超声心动图分割的方法和系统。 一种方法包括获得超声心动图像并使用一对一维（1D）轮廓在超声心动图中定义搜索空间。 该方法还包括使用由限定的搜索空间内的非局部时间先验约束的基于能量的功能，以利用1D轮廓自动分割心脏结构的轮廓。
