THE 3D VISUALIZATION OF THE PULMONARY VENOUS SYSTEM OF CHINESE PEOPLE / 解剖学报

ABSTRACT

Objective To build a digitized 3D model of the pulmonary venous system of Chinese people for the purpose of providing anatomic information of the pulmonary venous system for anatomic teaching,imaging diagnosis and surgical operation of pulmonary diseases. Methods The primal images from the first Chinese visible human data set of chest were converted into image sequence only cantaining the sections of pulmonary veins after manual registration and image segmentation.Then these images were imported into 3DMed software to build a 3D model of the pulmonary venous system through threshold registration algorithm. Results The three dimensional structures of the pulmonary venous system were reconstructed entirely.All reconstructed structures could be displayed individually or jointly,and could be rotated continuously on any plane.Conclusion The branches and the spacial characters of the pulmonary venous system can be clearly shown on the reconstructed 3D model.It will help anatomy teaching and provide morphological data for image diagnosis and lung operations.
