Abstract :
A two-dimensional phased-array ultrasonic probe is modified so that it can be scanned to obtain 3-D information. Offline, the endocardium of the left ventricle (LV) in the images is outlined, the endocardial surface is reconstructed numerically, and the resulting 3-D surface displayed. The results from studies on ten anesthesized dogs and four patients are presented. Although problems of smoothing and rendering the images remain to be solved, the method appears to provide information on patients during surgery that can not be obtained by other means
