The branching patterns of pulmonary arteries and veins vary greatly in the pulmonary hilar region and are very complicated. We attempted to reconstruct anatomically correct images using a freeware program. After uploading the images to a personal computer, bronchi, pulmonary arteries and veins were traced by moving up and down in the images and the location and thickness of the bronchi and pulmonary vasculture were indicated as different-sized cylinders. Next, based on the resulting numerical data, a 3D image was reconstructed using Metasequoia shareware. The reconstructed images can be manipulated by virtual surgical procedures such as reshaping, cutting and moving. These system would be very helpful in complicated video-assisted thoracic surgery such as lung segmentectomy.
肺动脉和肺静脉的分支模式在肺门区域差异很大，而且非常复杂。我们尝试使用一款免费软件程序重建解剖学上正确的图像。将图像上传到个人计算机后，通过在图像中上下移动来描绘支气管、肺动脉和肺静脉，并将支气管和肺血管结构的位置和厚度表示为不同大小的圆柱体。接下来，根据所得的数值数据，使用Metasequoia共享软件重建三维图像。重建后的图像可以通过虚拟手术操作进行处理，如重塑、切割和移动。这些系统在诸如肺段切除术等复杂的电视辅助胸外科手术中会非常有帮助。
