Computer-assisted instruction in radiology.

We developed an interactive computer system to support various educational uses. The system allowed numerous instructors to create lessons or tests in a flexible, personalized fashion. As a pilot project, the system was used to develop and administer a computer-driven final examination in a didactic radiology course for second-year medical students. It was our objective to change the examination into an enjoyable experience that would also bring about long-term learning gains. The computer added immediate feedback to the testing situation.

A computer system to monitor radiology department activity: a management tool to improve patient care.

A microcomputer system has been developed and installed at the Mallinckrodt Institute of Radiology to monitor the moment-to-moment activity in a radiology department. Data about department performances are collected, summarized, and displayed in graphs and tables on terminals at stations throughout the department. The system is currently used to monitor a wide variety of functions including patient waiting time, report production time, film-library operations, equipment maintenance, and room use. Since the displays are updated in real-time, it is possible to identify and address problems as they occur, thereby providing a method of evaluation that leads to improved performance as related to patient care.
