摘要 目的应用数字化技术构建手的骨骼血管等解剖结构,探讨手解剖结构的数字化虚拟技术。方法采用3具新鲜成人手标本,灌注前行CT预扫描,经自凝牙托材料及以硫化汞灌注处理4~24h后再进行CT扫描共获取220层数据集,利用Mimics软件对图像进行配准、分割、标识、重建手的外形、骨骼、动脉、指伸屈肌腱、神经等结构。结果建立了基于解剖结构的可视化手模型,各结构可单独、联合显示,可旋转缩放,模型透视及多剖面显示,血管管腔显示中空逼真,手部神经可部分显示。结论手可视化模型可为临床提供三维形态学资料,也为虚拟现实技术提供数字化模型。 Objective To reconstruct anatomical structures and establish visible model of the hand and evaluate some key techniques of digitized virtual hand. Methods Three hands were scan and then peffused by self-curing denture acylic and cinnabar. With the datum from CT-scan of the specimen of perfuscd hand(cryoprescrved 4-24 h), such anatomical structures as contour, bone, artery, extensor tendon, flexor tendon and nerve of hand were constructed by software of Mimics 10.01 and measured. Results The visible hand model based on anatomical structures was established and main anatomical structures were exactly showed. Each structure was displayed by the multiform solitude or combination. Vessel lumens was displayed hollow and fidelity. The hand nerve can the part demonstrate that can earnest reflect the normal human body nerve contour anatomy characteristic. Conclusion The visible hand model can provide 3D morphological data for clinical practice and research, as well as provide digitized model for virtual reality.
