Abstract

Contrast-detail (CD) analysis was used to compare the low-contrast detection capabilities of expert observers using different array-type scanhead technologies. Five expert observers viewed five different contrast targets to obtain CD curves for each scanhead. Differences in CD curves are interpreted in terms of the image contrast, resolution, and noise. It was found that differences in low-contrast detectability were due to differences in beam properties. Clinical images obtained during patient examinations are used to show how some clinically relevant tasks are distributed in their contrast and size.
