三维造型软件建立脑动脉虚拟三维模型的方法研究

探讨了应用三维造型软件建立脑动脉虚拟三维模型的方法。对46例具有颏顶位的正常脑血管DSA资料进行分析整理,选取具有代表性的DSA资料作为蓝本,利用三维制作软件3D Studio MAXR3创建虚拟的脑动脉系统模型。结果显示:虚拟脑动脉系统与DSA图像相比,在形态上具有相似性,在视觉上更容易理解血管的三维空间关系;通过将该虚拟模型文件复制成多个副本,稍加修改即可建立具有不同解剖变异的多个模型;在临床教学上能够帮助学习者建立并加强对脑动脉三维结构及其与脑动脉瘤空间关系的认识。以上结果表明,由软件方法建立的脑动脉虚拟三维模型能够逼真显示脑动脉系统的三维空间结构,可作为脑血管疾病虚拟研究的形态学基础。

Study on the Methods for Establishing Virtual Three-dimensional Models of Cerebral Arteries with the Three-dimensional Moulding Software

This study was conducted to establish the methods of virtual three-dimensional cerebral arteries models by use of three-dimensional moulding software. The virtual models of the cerebral arteries were established using the three-dimensional moulding software of 3D Studio MAX R3 with 46 cases of normal cerebral DSA image as the original. The results showed there was similarity in appearance between the virtual cerebral arteries and DSA image. This is of benefit to understanding the vascular three-dimensional spatial relation in visual sense. Several models of different variant anatomy could be easily established on the copy files of the virtual cerebral arteries model. The virtual model could help learners to create and increase the three-dimensional space concept of arteries and aneurysms in clinical teaching. The results indicated that the virtual three-dimensional cerebral arteries models could display the three-dimensional spatial relation of the cerebral arterial system distinctly, and could serve as a morphologic foundation in the researches on vascular disease.
