There are many hospital information systems (HIS) in Japan. However, still its application is limited to information processing except for image data. Recent advances of computer technology, optical technology for high-speed data transmission and storage system, and display technology for high-resolution images bring the possibility of image data management of a hospital wide (PACS; Picture Archiving and Communication System). This paper describes the technical possibility of an image data management system of nuclear medicine images and also the relation between HIS and PACS. It is known that the image data of nuclear medicine is between 1 to 3GB in a large hospital on a yearly basis. It was found that this quantity falls in a capacity of recent optical disk data filing system such an optical juke box using 5" optical disks or 12" optical disks. Also data transmission of a local area network has almost enough capacity and speed for daily nuclear medicine image data. Nevertheless, there is a problem on the image data transmission between each modality. In 1985, the ACR (American College of Radiology) and NEMA (National Electrical Manufacturers Association) introduced a standard interface protocol for medical image data exchange. In 1987, also MIPS (Medical Imaging Processing)-87 interface standard had beed introduced in Japan according to the ACR-NEMA-85 standard. After that, some enhancements were done on those two standards and then called ACR-NEMA-88 and MIPS-89. However, the standards have yet to contain information exchange protocol between HIS and PACS.
