The User Interface Study Group at the University of Arizona is investigating the interaction of Radiologists with digital workstations. Using the Arizona Viewing Console we have conducted an experiment to compare a digital workstation with a particular conventional reading process used for cases from a local Health Maintenance Organization. A model consisting of three distinct phases of activity was developed to describe conventional reading process. From this model software was developed for the Arizona Viewing Console to approximate the process. Radiologists were then video taped reading similar sets of cases at each workstation and the tapes were analyzed for frequency of hand movements and time required for each phase of the process. This study provides a comparison between conventional reading and a digital workstation. This paper describes the reading process, the model and its approximation on the digital workstation, as well as the analysis of the video tapes.
