Visual interaction in diagnostic radiology

The concept t of f Visual is al Interaction t r i is introduced as the process s which i links i s perception and problem-solving l -s l i such that t problem-solving l -s l ing is affected ted by what is seen, , and conversely, ersely, what is seen and perceived i is affected f cted by the current state t t of the problem-solving l -s l ing process. ess. This i paper describes i the development of a cognitively-based iti l se model of the visual l interaction process in diagnostic radiology, i logy, and shows how aspects of this model are being incorporated into the design i and implementation t ti of an intelligent computer-based radiological l i al assistant. In order to achieve this, , it is necessary r to extract information about the nature and type of knowledge ledge involved l in this process, ss, and then to determine how that knowledge l e is used to accomplish the task of radiological l i l diagnosis. sis.
