Our present study indicates that three dimensional reconstruction of transesophageal echocardiographic images could display multi-regional three dimensional structures of heart and great vessels,including superior vena cava,ascending aorta,right ventricular outflow tract, pulmonary artery and left heart,with clear,visual and stereoscopic imaging.The regional structures could be displayed at different levels of stereo-anatomic-sec-tions and in different orientations of rotating stereo-images,which could provide accurate three dimensional anatomical information for cardiac stereo-morphological study and definition of spatial location and size of cardiac abnormalities.展开更多
