A radiology information system (RIS) and picture archiving and communication system (PACS) are computer systems used in radiology departments to store, manipulate, and distribute patient radiological data and images. PACS provides economical storage and convenient access to medical images from different modalities (source machines). The principles of PACS were first discussed in 1982 by radiologists. RIS and PACS integrate imaging modalities, secure networks for transmitting patient information, workstations for interpreting images, and archives for long-term storage and retrieval of medical information to help make better diagnoses.
