Computed Radiography (CR) is a fully digital technology that uses an imaging plate (IP) made of photostimulable phosphor instead of traditional film. The imaging plate is housed in a special cassette and placed under the body part or object to be examined and the x-ray exposure is made. Once the image is captured on the plate, the plate (cassette) is fed into a scanner which reads the image and saves it.

Digital Radiography (DR) is an advanced form of technology where an X-ray sensor (Detector) is used instead of traditional film or CR cassette. Advantages include time efficiency by having the X-ray image captured directly onto a detector that in near realtime is saved as a digital file. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.
