【摘要】：医学影像归档与传输系统（Picture Archiving and Communication System,PACS）是目前医院信息化、数字化发展的重要项目之一。目前流行的PACS系统主要是基于C/S模式的，必须在客户端安装相应的图像浏览工作站。图像浏览工作站的兼容性很差，不能实现跨平台，在部署整个PACS系统的时候需要有专门的技术人员进行施工部署，同时客户端软件费用昂贵，对客户机要求也很高，推高了部署成本。而基于WEB的PACS系统，则可以实现大范围的共享、文件传输，而且客户端浏览器分布广泛，对客户机要求很低。同时在部署时，只需部署服务器，可以方便整个系统的维护与升级，降低维护成本。最主要的是可以为病人提供一个查看自己的病情的一个渠道。本文结合国内外对基于WEB的PACS系统的发展，分析了当前基于WEB的PACS系统的优缺点，提出了合理架构医学影像WEB服务器和优化影像传输的解决方案。在已有的PACS系统的基础上，架构了一款医学影像WEB服务器，提高了系统资源的利用率，加快了图像处理速度；提出了图像分块和多图层的图像传输技术，减少了图像数据传输量，有效地提高了图像的传输速度。本课题是基于DICOM标准、B/S模式、通过FastCGI以PHP脚本访问图像处理服务的方式架构了一种基于WEB的PACS系统。通过采用浏览器客户端进行图像和影像展示、服务端进行数据提供、影像处理的模式，减轻了客户端的处理任务，有效的降低了对客户端硬件的要求，，有利于实现系统的瘦客户端化、移动化、跨平台化。目前国内对基于WEB的PACS系统的研究还不成熟，相关的很多问题还需要进行深入的研究和探讨，如图像传输方式、图像信息获取方式、整个WEBPACS系统架构的合理优化等。虽然基于WEB的PACS系统的总体性能还没有达到C/S模式的水平，但是随着网络环境的基础设施的完善、计算机与网络通信技术的飞速发展，基于WEB的PACS系统的发展优势会越发明显。
[Abstract]:Picture Archiving and Communication system (PACSs) is one of the most important projects of hospital information and digital development. At present, the popular PACS system is mainly based on C / S mode, it is necessary to install the corresponding image browsing workstation on the client side. The compatibility of the image browsing workstation is very poor, so it can not realize cross-platform. When deploying the whole PACS system, special technicians are needed to carry out the construction and deployment. At the same time, the client software is expensive and the client is very demanding, which pushes up the cost of deployment. And the PACS system based on WEB, The client browser is widely distributed and requires very low requirements for the client. At the same time, when deploying, only the server can be deployed, which can facilitate the maintenance and upgrade of the whole system. Reduce maintenance costs. The main thing is to provide a way for patients to see their condition. Combined with the development of PACS system based on WEB at home and abroad, this paper analyzes the advantages and disadvantages of the current PACS system based on WEB, and puts forward a reasonable solution to construct the WEB server of medical image and optimize the image transmission. A medical image WEB server is constructed, which improves the utilization rate of system resources and speeds up image processing. The image transmission technology of image block and multi-layer is put forward, which reduces the amount of image data transmission. The speed of image transmission is improved effectively. This thesis is based on DICOM standard / B / S mode, and constructs a kind of PACS system based on WEB by PHP script accessing image processing service through FastCGI. By using browser client to display images and images, the server can provide data. The mode of image processing lightens the processing task of client, effectively reduces the requirement of client hardware, and is helpful to realize the thin client and mobile of the system. Cross-platform. At present, the research of PACS system based on WEB is not mature, and many related problems need to be deeply studied and discussed, such as image transmission, image information acquisition, Although the overall performance of the PACS system based on WEB has not reached the level of C / S mode, with the improvement of the infrastructure of the network environment and the rapid development of computer and network communication technology, The development advantage of PACS system based on WEB will become more and more obvious.
