Abstract
Displays (4) (pseudocolor mappings) available on a standard color TV are compared using 2 series of images (100 normal [human] brains and 100 normal livers) with 50 computer-simulated lesions superimposed on each set. Observers (4) viewed the sets of images in such a way that the order of the display methods for both organs formed 2 orthogonal Latin squares. The observers were asked to locate and rate, on a standard scale, the most apparent area in each image. ROC [receiver operating characteristic] analysis was applied. The heated-object spectrum was a useful display for brain images. The choice of display depends on the organ imaged.
