摘　　要：医学图像及其衍生的知识是医学教育中的一个关键学习部分 ,透过不同的图像模式 ,可以使医生及医科学生更有效地学习人体的体内结构 而计算机可视化技术最近的发展正满足了医生、外科医生及医科学生与日俱增的需求 ,为深入地了解人体生理学及病理学提供了宝贵的资料 本文提出了一个网上交互医学学习系统 ,并提供了一个虚拟现实工具包以支持二维医学图像序列观察、体数据和表面数据的三维可视化、目视放大镜 ,以及医学数据的交互变形模拟 其中人体组织物理特性的模拟以有限元法为基准 ,通过优化而获得有关的变形模型参数 该工具包可应用于个性化的二维及三维数据场可视化。Image and their derivatives form the key learning components in medical education Medical students and doctors learn to examine the human body through many different imaging modalities, which facilitate them to inspect the internal structure of human bodies The recent developments of computer visualization technology meet the ever growing need for doctors, surgeons, and medical students to gain valuable insight into human physiology and pathology In this paper, we have developed a web based interactive medical learning system with the advanced VR toolkit that supports 2D medical image sequence viewing, 3D visualization of both volume & surface datasets, visual magnification lens, and interactive deformable simulation of medical data in which the physical properties of human tissues are simulated by heuristic optimization against finite element model The toolkit we have developed supports personalized 2D/3D visualizations, optimal learning & planning, and on line interactive medical education
