Automatic detection and quantification of regional wall motion, LV function and remodeling using 2 D echocardiographic imaging

A system using two-dimensional echocardiography for quantitative assessment of left ventricular wall motion abnormalities, function, and shape has been developed. The computer system is used for digital image acquisition, storage, and quantitative analysis. This system can acquire and store echocardiographic images with no quality degradation, assist the operator in the contouring process, automatically detect wall motion abnormalities, and automatically perform global and regional distortion and expansion analysis. The system automatically provides information on six ventricular walls, after assisted contouring of digitally stored apical echocardiographic images. Simple and expressive indexes have been devised for the characterization of ventricular shape expansion and distortion
