Abstract

This paper presents a new system of echocardiographic visual processing and quantitative analysis, which can be used in computer aided diagnosis. Detection of the left ventricular boundaries in cardiac images is essential for the quantitative analysis. Our new approach incorporates a priori knowledge of heart geometry (a set of constraints), its brightness distribution, and Sobel operator detection in polar coordinate into the boundaries detection algorithm. Then we employ the outline chain-code tracking technique for echocardiogram computation and quantitative analysis. The procedure is demonstrated by using echocardiograms of the human heart.
