Research And Design Of PACS Workstation And Relative Technology Based On DICOM3.0

Picture access and communication system (PACS) is an information system used to manager pictures which are talced by medical equipment such as CT,MR in hospital. PACS is generated in 70's. It is not developed fast until the DICOM is brought forward by ACR-NEMA in 80's. As a big complicated system,PACS is to join many different systems. So it is important and difficult to find an actual scheme.DICOM means digital image communication in medicine. It is a standard communication protocol based on TCP/IP in medicine. It defines abstract patient object and other relative information in detail. It is an international hotspot of study and application especially used in PACS now.The author discusses PACS doctor workstation and relative technology in this article. The doctor workstation is used to show picture,so we should understand the file format,which is described in the second chapter. In that chapter,the author also describes the DICOM 3.0's specialty. The third chapter describes the whole framewith the "access by different level" technology. The fourth chapter describes everyinterface and realization method,and introduces the doctor workstation's design and realization. The fifth chapter describes some kind of technology which are accessing the DICOM information,adjusting the window width and window center,measuring the area,length and angle. The sixth chapter brings forward some improved direction.
