The Key Technologies in Realization of PACS
实现医学影象存档和传输系统中的若干关键技术

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.
