title: Contrast and latitude of CT hard copy: an ROC study.
abstract: A decision between film and paper for CT hard copy must be based on the different latitudes of the two media. The author conducted a receiver operating characteristic (ROC) analysis in which image information was matched to the characteristics of the recording media by adjusting both the window width of the display and the monitor contrast. Under these conditions, film images were found to be superior to print images for detection of noise-limited features. It is proposed that if the same optimization procedure were applied to clinical CT scans, the information content of the images could be increased.
