Computed Radiography stores the digital image on an imaging plate before transfer.

Computed Radiography stores the digital image on an imaging plate before transfer.

• A. Film
• B. Imaging plate
• C. Direct digital detector
• D. Image intensifier

Answer: (B)

In computed radiography, the image is stored on an imaging plate that contains a photostimulable phosphor. The plate traps energy during exposure, creating a latent image. When the plate is placed in the CR reader, a laser stimulates the phosphor and releases the stored energy as light, which is then converted into a digital image. The plate is erased and ready for reuse after this readout. This storage-on-a-plate approach distinguishes CR from traditional film (which uses chemical processing), direct digital detectors (which capture and transmit the image immediately without a plate), and image intensifiers (used in fluoroscopy, not as a storage medium for CR).
