title: Management and transmission of DICOM files using PC to PC multicasting methodology.
abstract: The PACS system built and used in hospitals nowadays has quite significant overload on its central server because of both treatment of very large data and full management of medical images. We suggest a distributed communication and management methodology using PC to PC multicasting strategy for efficient management of medical images produced by DICOM modalities. It is absolutely necessary for reducing strict degradation of PACS system due to large size of medical images and its very high transport rates. DICOM PC to PC component is composed a service manager to execute requested queries, a communication manager to take charge of file transmission, and a DICOM manager to manage stored data and system behavior. Each manager itself is a component to search for requested file by interaction or transmit the file to other PCs. Distributed management and transformation of medical information based on PC to PC multicasting methodology will enhance performance of central server and network capacity reducing overload on them.
