Abstract

Clinical evaluation of CT localization devices for chest imaging have demonstrated the advantages of wide dynamic range and edge enhancement produced by image processing. Major disadvantages in relation to film screen radiography are inferior spatial and temporal resolution. An observer detection study utilizing digitized film screen radiographs of patients with diffuse small pulmonary nodules were performed. Relatively low levels of spatial resolution are required for the detection/discrimination of these abnormal pattern types. More complex observer detection studies are required to determine the spatial resolution requirements for electronic digital radiography of the chest.
