title: Critiquing the process of radiologic differential diagnosis.
abstract: ICON is a developmental expert system designed to critique the process of radiologic differential diagnosis. To use ICON, a physician outlines (1) findings observed in a chest radiograph, (2) a small amount of clinical information describing the patient, and (3) a proposed diagnosis. ICON critiques the appropriateness of that diagnosis in detail, analyzing why and how well the findings serve to confirm it, or to rule it out. ICON may also suggest further information to look for. ICON explores the design issues involved in critiquing the process of differential diagnosis, and is currently implemented in a limited domain: the radiographic diagnosis of a lung mass in a patient with Hodgkin's disease.
