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.
