Computed radiography is a digital imaging technique that uses special imaging plates to capture X-ray images. These plates are coated with a photostimulable phosphor that stores the X-ray energy. After exposure, the plates are scanned by a laser in a CR reader, which converts the stored energy into a digital image. This method offers several advantages over traditional film radiography, including faster image processing and the ability to enhance and manipulate images digitally. Computed radiography is widely used in medical settings, as it improves workflow and reduces the need for chemical processing associated with conventional film.
