摘　　要：目的 创建与人体解剖结构一致的仿真主动脉弓三维快速成型模型,探讨其对促进规划和执行主动脉弓外科手术的帮助,为构建个体化人工血管支架及3D打印生物组织或器官进行前期准备.方法 对正常成年男性进行胸部CT扫描,获得该男子主动脉弓原始CT数据（DICOM）,通过Mimics 10.01软件对DICOM数据处理,分割出主动脉弓的区域,计算主动脉弓三维立体模型,导出三维模型数据文件（STL文件）,最后通过3D打印机打印出主动脉弓三维模型.结果 基于CT获得的胸部解剖结构的数据,通过MIMICS 10.01软件进行处理并导出STL格式文件后,可直接用3D打印机打印出与人体主动脉弓解剖结构基本一致的主动脉弓模型（比例1∶1）.结论 快速成型技术制备的主动脉弓模型对手术规划有临床意义,有助于构建个体化人工血管支架及3D打印生物组织或器官.Objective To create an anatomical correct 3D rapid prototyping （RP） model for a volunteer＆#39; s aortic arch and investigate the significance of aortic arch model for surgical planning.To make the early preparations for the mannufacture of individualize artificial vascular stents and 3D printing with biological tissue or organ.Methods Based on the extracted 3D contour image from volunteer＇ s chest CT data,the custom-made artificial aortic arch was designed with mimics 10.01 software and form 3D printing STL file.And then a aortic arch model was printed out by 3D printer.Results The data acquired by CT scanner can be rapidly prototyped after being edited with Mimics 10.01 software and directly used by 3D printing system to construct a aortic arch model （1∶1）.Conclusion The artificial 3D aortic arch model has significance in surgical planning and great help for the mannufacture of individualize artificial vascular stents and 3D printing with biological tissue or organ.
