dc.description.abstract Historically, gray scale has been the standard method of displaying univariate medical images. A few color scales have been proposed and evaluated, but have had little acceptance by radiologists. It is possible that carefully desired scales might give lesion detection performance that equals gray scale and improves performance of other tasks. We investigated 13 display scales including the physically linear gray scale, the popular rainbow scale and the other 1 1 perceptually linearized scales. One was the hot body (heated object) scale and the other 10 were spiral trajectories in the CIELAB uniform color space. The experiments were performed using signals added to white noise and a statistically defined (lumpy) background. In general, the best performance was obtained using the gray scale and the hot body scale. Performance for the rainbow scale was very poor ( about 30% of gray scale performance). en_US
