Research Of PACS System On Image Processing And Communicative Design Method

With the fast development of Information Technology and improvement of the computer application technology, the new generation of information system for medicine has expanded from the separate HIS (Hospital Information System), RIS (Radiology Information System) into the integrate hospital management Information system which including patient information, medical image and the management information in medicine. PACS (Picture Archiving and Communication System) is an important part of the integrate hospital management information which represents the upmost level in the application of medical information system.The article analyses and studies some key technologies involved in setting up a PACS. It introduces the DICOM (Digital Imaging and Communications in Medicine) standard and discusses details the research of communicative design method; It discusses the importance of image compression in PACS, and the article introduces some image processing algorithm used in system, especially the Wavelet Transform and JPEG standard , which have been adopted by the systems in hospital. At last, some image processing in PACS are also explained in this paper.The key technologies have been used in some practical PACS systems, and achieved excellent effect.
