Data management and radiotherapy.

The realization by radiation therapists that computerized patient information is a valuable resource is slowly evolving. The uses of this data include business, quality control, and research applications. Computer applications in these areas have been limited due to the small numbers of patients and the complexity of radiation therapy problems. Reductions in costs and improved programming techniques over the last decade have made information processing computer systems feasible. Measureable progress has been made in the areas of billing and scheduling systems, improved department data handling systems, and increased participation in cooperative groups with increased data handling capability. A review of costs in terms of dollars, time, and effort supports the use of information processing systems in therapy.
