由于缺乏计算机自动分析超声心动图图像的方法，使用二维超声心动图对左心功能的定量研究一直受到限制。以前的计算机努力是将二维超声心动图的视频输出数字化，但这种数字化方法有很大的局限性。开发了一种直接数字化的方法，该方法提高了信噪比，从而改进了心内膜和心外膜边界的自动检测。有了这些边缘的定义，可以逐帧进行左心室全局和局部分析，以便可以在整个心脏周期中评估心功能的动态变化。在二维超声心动图采集和图像处理方面的进一步技术进步应该允许计算机实时处理二维超声心动图数据。
Quantitative studies of left ventricular function using 2-dimensional echocardiography have been limited because of a lack of computerized methods to automatically analyze the echocardiographic images. Previous computer efforts have been directed at digitizing the video output of the 2-D echocardiogram, but this digitizing method has significant limitations. A direct digitization method that produces improvement in signal-to-noise ratio and, subsequently, improved automatic detection of endocardial and epicardial borders, was developed. With definition of these edges, left ventricular global and regional analysis is possible frame by frame so that dynamic changes in cardiac function may be assessed throughout the cardiac cycle. Further technologic advances in 2-D echocardiographic acquisition and image processing should allow computer processing of 2-D echocardiographic data in real time.
