To develop the hospital information system, the radiological information system, and the picture archiving and communication system for our new hospital, we analysed the data volume at each step of the flow in our present film-based system. After that, we used a small PACS, and it indicated the problems in it. From the analysis of the data volume of the film-based system, it was found out that digital data should be compressed, and prefetching techniques should be employed for digital PACS. Several types of display terminals had been proved to be necessary for different purposes. An RIS connection was thought to be obligatory to avoid incorrect input of ID on the image. Image input terminals should have edit functions for easy recognition of the image information. Taking account of these requirements for digital PACS, we are developing an actual total PACS.
为了开发我们新医院的医院信息系统、放射信息系统和图像存档与通信系统，我们分析了当前基于胶片的系统中流程各步骤的数据量。之后，我们使用了一个小型PACS，它显示出了其中存在的问题。通过对基于胶片的系统的数据量分析，发现数字数据应进行压缩，并且数字PACS应采用预取技术。已证明针对不同目的需要几种类型的显示终端。为避免在图像上错误输入ID，RIS连接被认为是必不可少的。图像输入终端应具有编辑功能，以便于识别图像信息。考虑到数字PACS的这些要求，我们正在开发一个实际的全功能PACS。
