中文摘要：

目的：建立具有解剖结构的虚拟手三维可视化模型。方法：选用首例中国女数字化可视人体数据集（CVH2）为原始数据源，用AdobePhotoshop软件先对手部的重要结构进行预处理和图像分割，再用VisualC＋＋6．0和VTK（Visualization Toolkit）可视化工具包作为开发平台，采用经典的MarchingCubes算法，对分割后的图像进行三维重建。结果：重建出了手部皮肤、桡骨、尺骨、腕骨（包括周骨、月骨、三角骨、豌豆骨、大多角骨、小多角骨、头状骨、钩骨）、第Ⅰ-Ⅴ掌骨、第Ⅰ-Ⅴ指骨第（包括近节指骨、中节指骨、远节指骨）的三维可视化模型，可以任意角度和比例大小对它们进行交互式观察，清楚地显示了它们在空间上的位置关系。该模型还实现了多模式的交互演示和角度测量、鼠标取点等实时交互功能。结论：为虚拟手的建模研究提供了三维可视化的解剖模型，探索了三维解剖建模的新的技术方法，并为进一步研究手的物理及运动生理建模建立了初步的技术平台。

英文摘要：

Objective： To establish a three-dimensional visible model of human hand. Methods： The hand images which were originally chose from the first chinese visible woman dataset （CVH-2） were pretreated and segmented with Adobe Photoshop software. And then the classical Marching Cubes algorithm was adopted and programmed in Visual C＋＋ 6.0 and Visualization Toolkit to reconstruct the segmented images into the three dimensional model by means of surface rendering. Results： A three-dimensional visible hand model was reconstructed, which consists of skin, radiu, ulna, carpal bone （including the scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitates and hamate bone）, metacarpal bones and phalanx. The model can be clearly observed from any arbitrary direction and scale to show the spacial location relationship.among the different anatomic structures of the hand. Moreover, The model could implement some real-time interacting functions, such as muti-pattern interacting demonstration, angle measure and mouse picking,etc. Conclusions： This study provides a three-dimensional visibly anatomy model for virtual hand＇s modelling research, and explores a new technology of the three-dimensional anatomical modeling. It also establishes the initial technical platform for the further study of human hands＇ physical and dynamic physiology modeling.
