摘要

Human observer performance in a search task was compared for viewing a single 2D image or a 3D image volume in cine mode. The test images consisted of designer nodules added to white noise backgrounds, or filtered noise backgrounds. In white noise backgrounds, performance increased dramatically when the entire volume was provided. In correlated backgrounds, no increase in performance was observed. These results are consistent with our previous findings for signal-known-exactly detection performance in single tomosynthesis slices or the entire reconstructed volume, where the inclusion of adjacent slices in the observer study did not result in a measurable increase in observer performance.
