摘　　要：目的:形象观察环跳穴的解剖结构和逼真模拟针刺过程,探讨穴位进针的安全性,提高临床针刺疗效。方法:在VOXEL-MAN平台中结合腧穴解剖学知识,利用计算机图形图像学技术对环跳穴相关肌肉组织进行交互式分割,对神经血管以数学建模的方式进行重建;以运行脚本的方式来获取环跳穴的三维进针动画。结果:完成环跳穴下解剖结构三维可视化,实现环跳穴在可视人体中的定位与表达,逼真模拟环跳穴的三维虚拟针刺过程,获得环跳穴的三维进针动画。结论:有助于立体显示环跳穴的解剖结构和逼真模拟针刺过程,有助于系统地观察到环跳穴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较好的基础。To observe the anatomic structure of Huantiao （GB 30） visually, to imitate the inserting process of the needle to explore the safty of needle insertion and improve the therapeutic effect of acupuncture in clinic. Methods Combined with anatomic structure of acupoint, muscles and other tissues related with Huantiao （GB 30） were interactively segmented in VOXEL-MAN with the computer graphics technology. Nerves and blood vessels were reconstructed by establishing mathematic model, and the needle-inserting animation of Huantiao （G-B 30） was obtained by running script file. Results The three-dimensional （3 D） visualization of Huantiao （GB 30） on needle inserting animation was accomplished, the spatial location and expression of Huantiao （GB 30） in the digitized virtuaI human body were observed, the virtual inserting process was imitated realistically, and the 3 D animation of needle insertion at Huantiao （GB 30） was created. Conclusion Building mathematic model is favorable for expressing the anatomic structure of Huantiao （GB 30） in 3-D space, imitating the process of needle insertion realistically and observing the spatial structure of the point and the around tissues, which can provide a solid foun- dation for the safety of needle insertion of acupoints and improve therapeutic effect of acupuncture in clinic.
