Paper Abstract

In this paper, we look at a different potentially useful method of behavior analysis, a method that may allow one to derive from the ROC confidence ratings of individual radiologists, a behavioral operating point that closely reflects the point where the radiologist would have decided to act or take no action on a case. This behavioral operating point appears appropriate for the calculation of cost benefit relationships and for studying how a radiologist shifts within ROC space when provided with Computer Aided Diagnosis (CADx) information.
