Research on DICOM file compression and offline storage platform

Digital Imaging and Communications in Medicine (DICOM) is an industry standard for the delivery of medical images and their information across a variety of devices, which standardizes the format of various medical images and supports both TCP / IP protocols. With the rapid development and popularization of network technology, it is required to communicate with PACS system through medical image browser and display PACS image and related information in medical image browser, so as to realize fast access of DICOM permanent object. This paper focuses on the main content and structure, which is related to DCM4CHEE system, by using PACS system based on message and service-oriented open source, such as DCM4CHEE, for the medical image browser and the server-side interaction. In this paper, DCM4CHEE system uses MYSQL as DICOM database and uses JBOSS as an application server to build a PACS system experiment. According to the basic needs of users and functional requirements, the system is divided into various functional modules, the design of its commonly used sub-system functions, the design of the basic functions of the system, according to the actual needs of research and study to make the overall design of the image file be browsed. The paper chooses Java as the development platform, carries on the inquiry into the image document and carries on the design and realization of it. The system has a good interactive interface, which can greatly enhance the users' experience.
