The number of radiologic studies quoted is the number of these undertaken during a one-year period at a university hospital with 650 beds, and reflects the actual number of each type of examination performed at a full PACS hospital. To determine the appropriate size of a short and long-term storage device, bearing in mind the design factors involved and the installation costs. International Nuclear Information System (INIS) The database information about characteristics of both storage devices and coding techniques are used by the third level functions to fit delivery/visualization requirements and to reduce archiving costs.ĭetermination of the size of an imaging data storage device at a full PACS hospital These functions are used to support the implementation of a storage management strategy.
The functions of the upper level work on image/video file on a logical basis, as they archive, move and copy image/video data selected by user defined queries. It manages file migration between high capacity media and low access time media. The medium level manages image/video files on a physical basis. They allow it to catalog devices and to modify device status and device network location. The functions of the lower level provide media management. Three levels of functions are available to manage the storage resources. The system can use different kinds of storage media, organized in a hierarchical structure. The database contains the pointers to the image/video files and the description of the storage devices. Because of their wide size, they are stored outside the database on network devices. Image/video files are not managed directly by the DBMS server. User workstations and servers are distributed along a local area network. Proper database structures have been defined to catalog image/video coding technique with the related parameters, and the description of image/video contents. This issue has addressed the project of the digital image/video database system that has been designed at IBM SEMEA Scientific & Technical Solution Center. The realization of image/video database requires a specific design for both database structures and mass storage management.
