What role does the scanner play in PSP imaging?

• A. Reads PSP plates
• B. Stores the image to USB drive
• C. Prints a hard copy
• D. Controls exposure for X-rays

Answer: (A)

In PSP imaging, the scanner’s job is to read the PSP plate and convert the stored latent image into a digital one. After exposure, the plate holds a hidden image in its phosphor layer. The scanner sweeps the plate with a laser, the phosphor releases light corresponding to the stored image, and detectors capture that light to produce the digital image for viewing and processing. The plate itself can be reused after proper erasure; transferring images to USB, printing a hard copy, or controlling X-ray exposure are handled by other parts of the system, not by the scanner.
