Abstract

The goal was to determine why viewing times are generally longer for images displayed on a monitor than on film for reading radiographic images. Eye-position of six readers was recorded as they searched 27 bone images on film or a monitor. Overall viewing time was longer with the monitor. Time to first fixate a lesion after search began and true negative dwell times were significantly longer for the monitor than film. Absolute number of clusters and dwell times were greater on diagnostic image areas on the monitor than on film, suggesting that more perceptual processing was taking place. This contrasts with the finding that the readers spent a greater percentage of their overall viewing time searching diagnostic areas on film than on the monitor. Twenty percent of the clusters for monitor viewing were on the image processing menu. The information that is processed during search of images on a monitor is different than on film. Additionally, the monitor has less spatial resolution and lower brightness than does film. These factors could lead to significant differences in the ways that readers search images and distribute their attentional and perceptual resources during search, which adversely influences monitor viewing time.
