Abstract

Computer-generated three-dimensional stereo images of the epicardial and endocardial surfaces of the left ventricle were displayed from data obtained with a biplane orthogonal roentgen video system. The silhouette of the opacified left ventricle was digitized from a video angiograph. The data were used to calculate the dynamic geometry of the ventricle and parameters such as curvature and stress. Continuous tone hidden surface displays of the ventricle were inscribed with isostress contours. The system is capable of obtaining biplane silhouettes of the ventricle at a rate of 60 pictures/sec. Dynamic displays of the beating ventricle can be obtained by recording sequential frames on a video disc recorder via a scan converter. The resulting sequence of frames can be played back in forward or reverse slow-motion or stop-action for detailed study.
