Paper Abstract

Chest radiographs recorded on DuPont WDR (wide dynamic range) film are used as input for digitization, image processing and display by an HCM graphic arts scanner interfaced to a mini-computer. The imaging chain is evaluated in terms of the MTFs of its components and its response to film density. Some advantages of using a very wide-latitude, constant-gamma film are discussed. A subjectively preferred unsharp masking algorithm is described and clinical examples are shown.
