Digital images produced by direct sensor systems are much larger than conventional radiographic film images because of monitor resolution and digital image file sizes. This difference in size may introduce difficulties when estimating distances (for example, during endodontic treatment). The aim of this study was to compare observers' estimates of distances(More)
The aim of this in vivo study was to compare approximal caries depth on storage phosphor plate images to conventional film. A Soredex Digora imaging plate was placed in a film bite-wing positioner behind a Kodak Ektaspeed Plus film package without lead foil. The effect of scattered radiation on film without lead foil with a storage phosphor plate at the(More)
The aim of this study was to analyze logarithmic contrast enhancement as compared with regular digital subtraction and to consider effects of image texture and observer experience. Radiographs of three different textures, including computer-stimulated lesions of various sizes and densities, were subtracted from radiographs taken before lesions were placed.(More)
