中国数字化可视人肺动脉系统的断面显示和三维重建

Cross-sectional study and three dimensional reconstruction of pulmonary arteries of Chinese digitized visible human

目的:对中国数字化可视人(Chinese visible human,CVH)横断面数据集的连续追踪观察及肺动脉系统的三维重建,研究肺动脉在肺脏内的分布特点。方法:对CVH数据集连续肺脏断面图像进行连续追踪观察,在断面上分割肺动脉,并对分割结果进行三维重建。结果:CVH肺脏断面图像清晰,可清楚显示肺动脉系统,分割后重建出肺内动脉系统,重建图像质量较高,最远可显示肺动脉的第5级分支。结论:研究实现了对CVH肺动脉系统的重建,为影像医学和肺脏手术提供了解剖学参考,而且可用于解剖学教学。

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.
