实现医学影象存档和传输系统中的若干关键技术

ＰＡＣＳ的重要性已被人们所认识，并且其技术在近１５ａ中得到了迅速发展。但是，实现ＰＡＣＳ仍然还有很多问题有待于解决。该文通过大量有关文献研究，指出并分析了实现ＰＡＣＳ过程中涉及到的关键技术，特别是对国际医学影象通信标准的内容进行了介绍；讨论了系统中有关影象存档和处理显示功能的软件设计方法；分析了常用的大容量影象数据存储方式，并给出了国内目前可行的解决方案。最后指出，为了跟上国际医学信息技术的发展潮

The Key Technologies in Realization of PACS

The importance of PACS has been recognized and progress of its technologies has rapid speed for the past 15 years. The Implementation of PACS still has many technical problems to solve. In this paper,firstly,the key technologies of PACS are presented and analyzed. Secondly,the standardization of Digital Imaging and Communications in Medicine of ACR/NEMA DICOM3.0 is described. Thirdly,Some software functions in image archiving,processing and display are discussed. Fourthly,a scheme for saving large data of medical imaging is proposed. Finally,the paper points out that in order to follow the stream of medical information,it is necessary to study and master the key technologies of PACS. It should to study and establish the standard for communication and store of medical image. In present condition,it should to study and set up small PACS. And large PACS will been established when there are mature conditions.
