Abstract


Along with fast development of network、computer and communication technology , Medical digital has become gradually a trend, PACS (Picture Archiving and Communication Systems) are in widespread use. However, PACS need to connect all the video equipment in hospital, there must be a universal communications standards to ensure that different imaging equipments of manufacturers can interconnect, for which, ACR(National electrical manufacturers association) and NEMA(National electrical manufacturers association) jointly developed DICOM(Digital Imaging and Communications in Medicine)standard.DICOM standard, the core of medical image information system field, defined a unified specification for transferred between Medical images and other digital information via various medical devices. DICOM standard can be directly applied to radiology information systems (RIS) and picture archiving and communications systems (PACS). Now, most medical imaging manufacturers have pledged to adopt the DICOM standard, and to provide DICOM 3.0 data communication interface. Full compliance with the DICOM standard has become the basic requirements and norms of PACS systems.The paper has a detailed analysis of the DICOM 3.0 standard from two aspects: the information structure and communication protocol. then , It has a deep research in implementation of the key services class (Storage Service Class C-STORE, Query service class C-FIND, Retrieve service class C-MOVE, etc.); Compiled application program related to DICOM standards by VC2005 and open-source toolkit DCMTK (DICOM TOOL KIT) to achieve the medical image query / retrieve function and use professional testing procedures JDICOM to test the software, test results indicate that the realization of functions in accordance with DICOM standards.The paper implements DICOM storage services, and query/retrieve services, and make doctors、patients and other information exchangers within the LAN are able to easily access the DICOM medical image information , realized information resource sharing.
