下肢骨畸形在线辅助诊断仿真系统

Online Auxiliary Diagnosis Simulation System for Lower Limb Bone Deformity

当前医生主要利用多张二维影像进行下肢骨畸形诊断,难于从多角度对畸形部位进行全面地观察,不利用于手术前详细规划.因此本文应用HTML5、JS和CSS等Web开发技术自主开发了一种下肢骨畸形在线辅助诊断仿真系统,实现了利用DICOM影像在线构建下肢骨和人工关节三维模型,全方位浏览三维模型,动态展示和对比观察DICOM影像,辅助诊断工具(包括测量工具、灰度变换、细节查看、精确定位),管理病人信息等多种所需功能.该系统集成了VTK、Cornerstone和Three等开源架构,具有实用性强、在线共享和便于扩展性等优点,为下肢骨畸形诊断和手术规划提供了一个高效有力的在线辅助平台.

At present, doctors mainly use multiple two-dimensional images to diagnose the bone deformities of lower limbs. It is difficult to comprehensively observe the deformed parts from multiple angles, which is detrimental to detailed planning before surgery. Therefore, the Web development technologies, such as HTML5, JS, and CSS, are employed to independently develop an online auxiliary diagnosis simulation system for lower limb bone deformities in this study.Various required functions are implemented, such as online 3 D modeling of lower limb bones and artificial joints based on DICOM images, 3 D model browsing in an all-round way, dynamical display and comparison between DICOM images,auxiliary diagnosis tools(including measurement tools, gray scale transformation, detail viewing, and precise positioning), and patient information management. The system integrates open source architectures such as VTK,Cornerstone, and Three. It has the advantages of strong practicability, online sharing, and easy scalability, providing an efficient and powerful online auxiliary platform for the diagnosis of lower limb bone deformities and surgical planning.
