Computed radiography (CR) is the use of photostimulable phosphor[1] as an image receptor. The image receptor is held in a similar casing (cassette) to that of the traditional film screen. Computed radiography harnesses the absorption of radiation, trapping electrons at energy levels via the process of photostimulable luminescence.

CR enables the transition of conventional radiography to digital radiography, by using existing x-ray equipments for conventional radiography 3.

Electron storage

The computed radiography plate has a thin layer of phosphor grains, known as a photostimulable phosphor. The plate is exposed to x-ray radiation[2] exciting the phosphor, exciting the electrons to be trapped in the lattice until inevitably they are stimulated by the second round of illumination.
