Both computed radiography (CR) and digital radiography (DR) require the use of digital technologies which rely on computer networks and high-bandwidth web facilities.

DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, which is then processed to produce a digital image.

CR uses cassette-based phosphor storage plates (PSP), which are then scanned by the computerized system into a digital format for image processing, archiving, and presentation. However, with DR, the whole procedure is digitized from X-ray detection onward.
