What device is used to read the imaging plate by scanning with a laser?

• A. The monitor
• B. The reader (processor)
• C. The processor's tape
• D. The computer's keyboard

Answer: (B)

Reading computed radiography images requires a device that scans the exposed imaging plate with a focused laser and converts the released light into a digital signal. That function is performed by the reader, also called the processor. The plate stores energy in its phosphor layer after exposure; when the laser sweeps across it, it stimulates the phosphor to emit light proportional to the stored energy. The reader detects this light and converts it into a digital image for processing and viewing. The monitor is only for displaying the final image, while a keyboard is for input; the reader's job is specifically to read and digitize the plate data.
