The use of digital imaging systems to replace conventional X-ray pictures and other imaging techniques. Though expensive to operate, digital imaging and storage systems o?er promising possibilities for transmission of clinical images within and between hospitals and community health-care units, providing fast access and remote working that will bene?t patients and health-care sta? alike. When security and con?dentiality are assured, images could be transferred via the Internet and teleradiology. In future, hospitals might be able to eliminate the costly physical transfer and storage of X-ray ?lms. The integration of PACS with hospital information systems in the NHS will (hopefully) facilitate the introduction of electronic radiology.... picture archiving and communications system (pacs)
