The Introduction to [Computers in] [Biomedical Research], Vol. III, evaluating accomplishments over a three-year period and predicting areas for future emphasis. Characteristics distinguishing recent computer systems from those in the past include increased complexity, flexibility, and capacity for improving health-care services. Work is being done to implement present image processing techniques and, in addition, to promote computer-aided instruction in regard to biomedicine. In the future, mathematical models combined with graphic and flexible forms of data presentation could become an integral part of research hospitals, monitored patient wards and clinics, and basic research laboratories. Interactive computer terminals and the attendant central processor software will be useful for hospital communications, for model building and hypothesis testing, for patient autointerview, for perusing files of data, and for other tasks requiring the transfer or analysis of data. 20 pp.
