In CR imaging, what term describes the plate that stores the latent image?

• A. ABC
• B. PSP
• C. DQE
• D. SNR

Answer: (B)

In computed radiography, the plate that stores the latent image is the photostimulable phosphor plate. This imaging plate is coated with phosphor crystals that trap electrons after X-ray exposure, preserving the captured image as a latent signal. When the plate is later read, a laser scans its surface and stimulates the trapped electrons to release their energy as light, creating a visible signal that’s converted into a digital image. The term PSP specifically names this plate, distinguishing it from performance metrics like DQE (detective quantum efficiency) or SNR (signal-to-noise ratio), which describe image quality rather than the physical plate.
