Experience with MARS (Missouri Automated Radiology System).

Since April 1970, the Department of Radiology of the University of Missouri has used an on-line computer system to record, encode, and retrieve all radiological consultations. The System has greatly speeded up delivery of typed reports without slowing down the radiologists using it, and provides an excellent mechanism for retrieving case material for teaching and research. The major drawbacks to the System are computer reliability and cost. We hope to overcome these problems by employing a smaller computer system dedicated solely to operation of the department, and by the addition of programs to handle business operations.
