摘要：

In this paper we report a method for displaying mitral valve motion of a beating heart in a three-dimensional (3-D) image reconstructed from twenty-eight different scanning plane tomograms, each of which consists of twenty successive ultrasonic B-mode images. A 3-D image consists of surface polygon sets to separate the internal and external regions of the heart. The 3-D image is smooth with lighting calculated from vertex normals bf polygons. The 3-D mitral valve motion image is obtained from repeated 3-D images in phase in one cardiac cycle. In addition, we display stereoscopic heart images which have angular viewing separation for viewing images, and we obtain spatial relationships of heart anatomy from such images.
