Practical note
DIGITAL INTRAORAL RADIOGRAPHY
M. MASTORIS, K. NIKOPOULOU-KARAYIANNI
SUMMARY Digital radiology is no longer restricted to the laboratory and several digital systems for the acquisition, storage and display of intraoral radiographs are now commercially available. Each of these systems has its own advantages and disadvantages. By using one of these systems, the general practitioner can take advantage of the possibilities of computer-based image acquisition and archiving. At this moment, the images produced by the current systems vary in size of the file, resolution and sometimes even in the way the image is created. This variation of image characteristics is due to several reasons, the main one being the different physical and technical characteristics, such as pixel size and number of pixels in the horizontal and vertical directions of the acquisition device. There are basically two methods to acquire digital intraoral radiographs. One method is based on Charged-Coupled Device (CCD) technology, and the other based on Storage Phosphor Plate (SPP) technology. This article presents the functional principle, the maximum theoretical resolution of the image and the advantages and disadvantages of the main systems for digital intraoral radiography.
KEY WORDS: Digital imaging, Intraoral radiography, Dental radiography.
