1 August 1990 FEASIBLE software supports the ROC evaluation of digital imaging systems
Author Affiliations +
A software package has been developed to aid psychophysical studies on diagnostic image quality. The program, called FEASIBLE, supports all phases of experiments to evaluate the diagnostic quality of PACS components, image acquisition and manipulation methods and display techniques. The software allows the user to design any such an evaluation study, to perform an arbitrary number of psychophysical sessions and to statistically analyze the collected data with the Receiver Operating Characteristics (ROC) technique. Furthermore, the calculated ROC curves can be plotted in graphs to be integrated in publications. Within the scope of the Dutch PACS project, a PACS research project jointly carried out by the Utrecht University Hospital, BAZIS and Philips, FEASIBLE has been used to investigate the diagnostic accuracy of the PACS prototype that was clinically evaluated. The package has been sent - upon request - to more than 20 scientists in the field of radiological imaging. This paper explains the backgrounds and the features of the latest version of the program, and the way to use it in an actual ROC study.
