Augmented Bloomgarden method. The volume contribution for contour point pairs above the true apex line (light gray region) contains both left ventricular (LV) cavity and myocardial tissue. Contour point pairs that lie between the true apex line and the prescription central axis contribute only myocardial tissue (dark gray region). The LV cavity volume in the augmented Bloomgarden method is computed by adjusting Equation (10) to subtract the myocardial tissue volume.
