Adding a microcomputer bar-code network to a minicomputer-based radiology information system

A bar-code terminal network under software control of a microcomputer was added to the minicomputer-based radiology information system at the Medical College of Georgia in Augusta. The bar-code network was specifically installed to address the inherent inaccuracies occuring when procedure information was entered at the time of registration before procedures were actually performed. Technologists now enter procedure data into bar-code terminals after procedures are performed, substantially reducing database errors. This approach allowed us to take advantage of a microcomputer product without the necessity of completely converting our highly customized information system software from minito microcomputer.
