The PACS system built and used in hospitals nowadays has quite significant overload on the central server of it because of both treatment of very large data and full management of medical images. We suggest a distributed communication and management methodology using Peer to Peer 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 Peer to Peer 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 Peers. Distributed management and transformation of medical information based on Peer to Peer multicasting methodology will enhance performance of central server and network capacity reducing overload on them.
