An educational system of VATS for residents of general thoracic surgeons by using personal computer

由于肺动脉和静脉的位置和分支的心囊远端表现出很大的个体差异，这些血管的相关数据是有用的胸surgeon. Methods：我们开发了免费软件，其中支气管和肺动脉和静脉可以标记的图像从CT（计算机断层扫描），已上传到个人电脑。然后，我们建立了一个系统，通过该系统可以重建三维（3D）图像，并可以使用免费软件进行3D图像分析来模拟手术。使用免费的三维图像分析软件，确定每个患者肺门区域的支气管、肺动脉和静脉的分布和分支模式，以重建三维图像，能够对重建的支气管和肺动脉和静脉进行虚拟整形和切割。

As the location and branching of pulmonary arteries and veins distal to the cardiac sac exhibit great individual differences, data related to these vessels are useful to thoracic surgeons.Methods : We developed freeware with which bronchi and pulmonary arteries and veins can be marked on images from CT (computer tomogram) that have been uploaded to a personal computer. We then established a system by which 3-dimensional (3D) images can be reconstructed and surgery can be simulated using freeware for 3D image analysis.Results : Using a freeware program for 3D image analysis, distributions and branching patterns of bronchus, pulmonary arteries and veins in the hilar region of each patient were ascertained to reconstruct a 3D image, enabling virtual reshaping and cutting of reconstructed bronchi and pulmonary arteries and veins.
