Which statement best describes the imaging plate's state after X-ray exposure?

• A. It immediately emits a full-resolution image
• B. It needs no processing and can be viewed directly
• C. It stores energy and remains excited until processed
• D. It leaks energy and cannot be read

Answer: (C)

After exposure, a computed radiography imaging plate uses a photostimulable phosphor that traps energy in its crystal structure. This creates a latent image—the plate is storing energy and is not yet readable. The plate stays in this excited, energy-stored state until it is processed by the CR reader, which scans it with a laser. The laser releases the stored energy as light, and that light is captured and converted into the digital image. The plate must then be erased so it can be reused. So the statement that best describes the plate’s state after exposure is that it stores energy and remains excited until processed.
