Building and using a data base to identify parameters to further improve diagnostic performance on the Toshiba computed radiography system Model 201

The digital imaging group at the University of Arizona Health Sciences Center Radiology Department is vigorously pursuing the development of a total digital radiology department (TDRD). One avenue of research being conducted is to define the needed resolutions and capabilities of TDRD systems. Parts of that effort are described in these proceedings and elsewhere. One of these investigations is to assess the general application of computed radiography (CR) in clinical imaging. Specifically the authors are comparing images produced by the Toshiba computed radiography system (Model 201) to those produced by conventional imaging techniques. This paper describes one aspect of that work
