A demonstration picture archiving and comniunication system (PACS) was developed using standard networking protocols. The systera was developed primarily to gain experience in digital image communications and optical disk usage as well as to raeasure perforittance factors to be used in the design of a substantially larger system. The system consists of a General Electric SIGNA MRI system connected via Ethernet to an IBM P5/2 Model 70, which serves as a gateway to a token-ring network. Resident on the token-ring, along with the P5/2, is an IBM AS/400 computer, an IBM System/36 with an optical storage subsystem and an IBM PS/2-based image review work station. Custom software was developed on each of the computers to control the flow of data and to manage the storage and retrieval of images. Standard TCP/IP software (File Transfer Protocol) is used to transfer the images from the MRI system to the P5/2. The images are converted into ACR/NEMA file format and made available to the communication and archiving system. Under AS/400 control, P5/2 resident programs copy a subset of the ACR/NEMA header information to an AS/400 database, and copy all of the image files to the optical storage subsystem for permanent storage. AS/400 programs were developed to enable database query operations. User-selected images are transferred from the optical storage subsystem either back to the MRI system or to the P5/2-based image review work station.
