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

This is a AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A337014. The abstract provided by the Pentagon follows: 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.
