In CR IP, the purpose of the storage capacitor within the DEL is to:

• A. Hold the latent image
• B. Speed up readout
• C. Prevent phosphor damage
• D. Increase exposure

Answer: (A)

In CR, the latent image is stored in the phosphor layer of the imaging plate by trapped electrons. When readout begins, the system scans the plate with a laser and converts the emitted light into an electrical signal. The storage capacitor inside the DEL holds that electrical signal long enough for the scanner to finish reading and for the analog-to-digital converter to sample it. This preservation of the signal ensures the latent image information is captured accurately in the digital output. It isn’t about speeding up readout, protecting the phosphor, or increasing exposure; those aspects are handled by other parts of the system.
