PSP stands for Photostimulable Phosphor.

• A. Photostimulated Particle
• B. Photostimulable Phosphor
• C. Phosphor Stimulated Particle
• D. Photo-stimulable phosphor

Answer: (B)

The main idea is the term used for the material in computed radiography that stores energy from X-rays and then releases light when stimulated. Photostimulable phosphor describes a phosphor that traps energy after exposure and can emit light when stimulated by a light source, such as a laser, during the plate readout. That stored energy-to-light process is the basis of how CR systems convert latent exposure into a digital image. Why this is the best choice: the phrase photostimulable phosphor matches the standard terminology. It correctly identifies the material as a phosphor and uses the established descriptor for its property—storing energy until stimulated to emit light. The other options either swap terms (particle instead of phosphor), place words in an awkward order, or use a hyphenated form that isn’t the conventional spelling in this context.
