基于网页的可视化网络医学影像平台设计

Design of visualized medical images network and web platform based on MeVisLab

随着"互联网+"发展的趋势,医务人员对医学影像的移动化也有了一定的需求。针对这一需求,本文提出了一种基于网页(web)的可视化医学影像平台。首先,本文分析了绘制医学影像的可行性以及技术要点,通过医学图像处理和科学可视化的跨平台应用框架(Me Vis Lab)对电子计算机断层扫描成像(CT)或磁共振成像(MRI)图像进行三维(3D)重建,并且封装成可扩展3D语言(X3D)文件。然后,应用第五代超文本标记语言(HTML 5)和网页编程图形库(Web GL)渲染引擎库,设计出专门为3D图像渲染的浏览器/服务器(B/S)系统,并利用该系统解析、渲染X3D图像文件。本文的研究结果显示,该平台适用于多个操作系统,便于实现医疗影像数据的跨平台化、移动化。最后,本文对医疗影像平台的发展进行了展望,指出web技术的应用将促进医疗影像数据的共享,也便于实现基于医疗图像的远程会诊和远程教学。

With the trend of the development of＂Internet ＋＂, some further requirements for the mobility of medical im ages have been required in the medical field. In view of this demand, this paper presents a web-based visual medical imaging platform. First, the feasibility of medical imaging is analyzed and technical points. CT （Computed Tomography） or MRI （Magnetic Resonance Imaging） images are reconstructed three-dimensionally by MeVisLab and packaged as X3D （Extensible 3D Graphics） files shown in the present paper. Then, the B/S （Browser/Server） system specially designed for 3D image is designed by using the HTML 5 and WebGL rendering engine library, and the X3D image file is parsed and rendered by the system. The results of this study showed that the platform was suitable for multiple operating systems to realize the platform-crossing and mobilization of medical image data. The development of medical imaging platform is also pointed out in this paper. It notes that web application technology will not only promote the sharing of medical image data, but also facilitate image-based medical remote consultations and distance learning.
