Automatic and Interactive Image Processing of 2-D Echocardiogramms for Analysis of Left VentricularDue to the noisy appearance and low reflected signal energy from boundaries characteristic for 2-D echocardiographic images, specific reflection properties and accuracies of automatic and manual border extraction are greatly reduced. Therefore digital processing of two dimensional echocardiogramms in our institution is focused on three basic areas:

However, the microbubbles contained in solutions are too large to pass a capillary bed. As a consequence, an echo-contrast effect on the lef
