In CR systems, which item is not typically utilized?

• A. IP reader/digitizer
• B. PSP IP
• C. protective layer
• D. chemical developer

Answer: (D)

CR imaging uses a reusable storage phosphor plate that stores the exposed energy and is read out by a dedicated reader. The PSP IP is the plate itself, and it includes a protective layer to guard the delicate phosphor surface from scratches and handling damage. After exposure, the plate goes to the IP reader/digitizer, which scans it with a laser and converts the released light into a digital signal for viewing. The plate is then erased and ready for reuse. A chemical developer isn’t used in CR because there’s no film to develop like in traditional film-screen radiography; digital CR relies on the laser readout rather than chemical processing.
