摘　　要：背景:虚拟现实技术与中医穴位相结合,可实现针刺的三维立体表达。目的:基于VOXEL-MAN和Micro-XCT-200机,通过对内关穴三维形态结构的可视化研究,进一步探讨穴位结构。方法:在VOXEL-MAN系统中结合腧穴解剖学知识,内关穴(PC6)邻近的肌肉分割后进行融合,神经血管进行三维重建;编写程序获得内关穴的三维进针动画,进行内关穴位的三维可视化和虚拟进针研究。通过Micro-XCT-200机对穴位的本质进行补充。结果与结论:完成了内关穴局部解剖结构的三维可视化,实现了内关穴在数字化虚拟人体中的定位与表达。运用Micro-XCT-200机对内关穴位的结构进行了研究,尚未发现新的组织。穴位局部三维重建有助于立体显示穴位解剖结构和逼真模拟针刺过程,有助于系统地观察针体和穴位周围各组织的空间位置关系,为探讨穴位进针的安全性、提高临床针刺疗效奠定了较好的基础。Micro-XCT-200机对内关穴位的结构研究,为"穴位立体构筑理论"进一步提供了实验依据。BACKGROUND： Based on the integration of virtual reality technology with acupoints, acupuncture can be expressed three-dimensionally. OBJECTIVE： To explore the structure of points through reconstructing digitalized three-dimensional visualization of Neiguan（PC6） structure based on VOXEL-MAN and Micro-XCT. METHODS： Muscles and other tissues adjacent with Neiguan（PC6） were segmented and merged based on the VOXEL-MAN system combined with the anatomical knowledge of acupoints; nerves and blood vessels were performed with three-dimensional reconstruction; the needle-inserting animation of Neiguan（PC6） was obtained by running script file. Three-dimensional visualization and virtual needle-inserting researches of Neiguan（PC6） were performed. Nature of the acupoints was detected by the Micro-XCT-200 machine additionally. RESULTS AND CONCLUSION： The visualization of the anatomical structure of local Neiguan（PC6） was completed, and the localization and expression of Neiguan（PC6） in the digitized virtual human were realized. TheNeiguan（PC6） structure was researched with Micro-XCT-200, and showed there was no new tissue. Local three-dimensional reconstruction of the acupoint structure could help to display the anatomical structure of acupoints and simulate the acupuncture process. It could also help to observe the relationship between the needle body and the surrounding tissues during needle-inserting, which supplying a good basis not only for exploring the security of needle-inserting, but also for improving the clinical effect of acupuncture. The research on the structure of acupoint Neiguan（PC6） by Micro-XCT-200 provides further experimental evidence for the hypothesis of three-dimensional acupoint.
