dc.description.abstractThis paper presents a new fully automated algorithm that extracts LV epicardial and endocardial borders from 2-D echocardiograms. The method is based on a radial search approach, which is the best way to use some a priori informations of the edges. A signature descriptor of contours is carried out. From that function and using Fourier series for extrapolation and tracking in some steps a good approach of edges is found. an extension of this algorithm to contour searching on a sequence of 2-D echograms covering the entire cardiac cycle is easily performed. From this approach over apical rotatied views a cylindrical integration method is used for estimating the left ventricular volume.
