Digital radiography is a form of two-dimensional x-ray imaging in which traditional light-sensitive and radiation-sensitive x-ray film and analog hardware have been replaced with a digital image capture device, usually consisting of a flat-panel detector, and computer-based equipment. The detector captures the images. The computer controls the operation of the system and manages the image acquisition in real time. Then it allows enhancing, processing, archiving and transferring the captured images digitally. Three-dimensional images are only possible using computed tomography (CT) technique, detailed information on this subject is available in the YXLON CT Handbook.
