Visual Detection and Localization of Radiographic Images

In conventional receiver-operating-characteristic (ROC) curve analysis of visual detection performance, the observer is credited with a true-positive response if a visual signal...

Radiographic Applications of Signal Detection Theory

Receiver operating characteristic (ROC) curves describe observer performance in the detection of small noiselimited signals such as the image of a 2 mm Lucite bead against a bac...
