摘　　要：目的:建立上胸椎前方入路重要解剖结构的三维可视化模型,为学习此区域的解剖和制定术前计划提供帮助。方法:采用第三军医大学提供的首例中国女性数字化可视人体数据集,选取T1椎体上缘到T5椎体下缘层面的连续断面图像,导入Photoshop CS中进行自动化批处理裁切后转变为JPEG图像。然后再分别导入3DDoctor3.5和Amira4.0两个软件程序中进行表面重建和体积重建。结果:表面重建模型可以旋转至任何角度,各解剖结构可单独或同时显示,可以从任何视角观察。体积重建模型可以提供横断面、冠状面、矢状面和任意斜切面的二维图像,能提供丰富的内部细节。结论:上胸椎前方入路重要解剖结构的三维可视化模型,能清晰地显示各个重要解剖结构的大体形态、空间位置和毗邻关系,十分有助于学习这一复杂区域的解剖和术前计划的制定。Objective：To establish the three dimensional （3D） visible models of the anatomical structures of the anterior approach to the upper thoracic spine（UTS） for anatomic study and preoperative planning of the UTS.Methods：Sectional images from the superior margin of the first thoracic vertebral body to the inferior margin of the fifth thoracic vertebral body were acquired through the Chinese Visible Human Female （VCHF） database which was collected by the Third Military Medical University.These images were imported into Photoshop CS,cut automatically and converted into a JPEG format.Surface and volume reconstruction were performed by 3D Doctor 3.5 and Amira 4.0 software programs on an ordinary personal computer respectively.Results：The surface reconstruction model could be rotated at any angle and observed from any direction.And the reconstructed structures of the anterior approach to the UTS could be displayed individually or as a composite with any other selected structure.The volume reconstruction displayed abundant internal details of the reconstructed images in transverse,coronal,sagittal,and random oblique sections.Conclusion：Three dimensional visible models of the anatomical structures of the anterior approach to the UTS based on the sectional images of VCHF can clearly display the morphology,spatial orientation and adjacent relationship of every structure.These models are very helpful to the anatomy study and preoperative planning of this complex anatomic region.
