[en] The Digital Imaging Network (DIN) Project is a collaborative effort involving the Department of Defense, Public Health Service, Veterans Administration, MITRE Corporation, university medical centers, and private industry. The objectives are to install, operate, and evaluate two different prototype DIN/picture archiving and communication systems (PACS), and to develop guidelines and specifications for operational DIN/PACS in military and civilian settings. The evaluation emphasizes clinical acceptance and utility, technical and operational feasibility, and impact on radiology department function and the clinical care process. New imaging devices being developed for combat use are evaluated to ensure compatibility with future DIN/PACS
