Fig. 1. Graph of receiver operating characteristic (ROC) curves for
radiograph interpretation from conventional radiographic film shows ranking of
four observer groups as measured by areas under curves. Nonparametric
(empiric) ROC curves are shown.

Fig. 2. Graph of receiver operating characteristic (ROC) curves for
image interpretation with high-resolution video monitors shows ranking of four
observer groups as measured by areas under curves. Ranking is same as that for
radiographic film, but areas are less in all four groups. Nonparametric
(empiric) ROC curves are shown.
