Paper Abstract

A Meta-analysis was performed on the data reported for observer performance studies comparing plain film and digital hard copy on lung interstitial disease and abnormalities of the bones of the extremities. Spatial resolutions from 5122 to 40962 were included. It is concluded that spatial resolution alone is not the determinant of success in observer performance. It is quite possible that an optimum is approached between 10242 and 20482 and that further improvement in performance will depend upon improvements in gray scale rendition.
