Objective：To explore the anatomical characteristics of the peripheral pulmonary arteries in lung by observing the cross-sectional images of Chinese digitized visible human and making three-dimensional reconstruction of the pulmonary artery system. Methods：A series CVH images of chest were consecutively observed, then the pulmonary arteries were labeled in these images. At last，the labeled images were inserted into computer to make three-dimensional reconstruction. Resultｓ：The pulmonary arteries could be recognized in CVH images and reconstructed. The three-dimensional images perfectly show the brunches of the pulmonary arteries, even the subsubsegmental arteries（fifth order） were able to be recognized. Conclusion：The research reconstructed and visualized the pulmonary arteries of the first Chinese Visible Human. The digitalized visible model of the pulmonary arteries can display the special conformation of this region using reconstructed three-dimensional images. It will help in anatomical teaching and provide morphological data for imaging diagnosis and operation of lung.
