When should a computed radiography imaging plate be processed to prevent loss of the latent image?

• A. As soon after exposure as possible
• B. Three minutes after exposure
• C. Five minutes after exposure
• D. Seven minutes after exposure

Answer: (A)

The latent image on a computed radiography plate is stored as trapped electrons in the phosphor after exposure. This stored energy is not permanent and slowly fades over time due to natural recombination and temperature effects. If you delay processing, the signal available during readout diminishes, which can reduce image brightness, contrast, and overall quality. Processing as soon after exposure as possible captures the stored information before significant fading occurs, giving the best possible image. Delays of several minutes allow more fading to occur, so they’re not as effective at preserving the latent image.
