Abstract
The method reported represents an intraventricular ultrasonic technique and a model of the left ventricle from which its volume can be calculated. The geometrical model used is a paraboloid of revolution. A spherical steerable transducer is used to measure intraventricular dimensions. An auxiliary device to the ultrasonic generator, which has been developed in our laboratory, triggers the measurements from predefined points during the cardiac cycle and stores the measured dimensions. The device could generally be used for measurement of static volumes.
