Objective To study a new computerized automatic method for endocardial boundary estimation and tracking in sequential echocardiographic images. Method Through analyzing the existing problems of the traditional fast marching method, the contour energy conception of the active contour model was introduced to improve the traditional fast marching mathematical model. Result The improved mathematical model was applied to sequential echocardiographic images and the experimental results showed that endocardial boundary can be accurately detected. Conclusion The introduction of contour energy conception enhances the stability and effectiveness while keeping the convergence velocity of the fast marching algorithm.
