JPEG 2000 Compression of Direct Digital Images: Effects on the Detection of Periapical Radiolucencies and Perceived Image Quality

摘要

Radiographic evaluation is an essential component of endodontic diagnosis. In recent years, direct digital imaging (DDI) has been introduced to replace or augment radiographic film. Studies comparing diagnostic accuracy of DDI and conventional film for detection of artificially created periapical lesions have revealed comparable results. Advantages of DDI have been reported as: (1) lower radiation exposure to patients, (2) elimination of chemical processing, (3) computer storage capability, (4) electronic transportation of images and (5) instantaneous capture of images.
