The CR reader unit scans the IP with a which device?

• A. Infrared Light
• B. Laser
• C. Sonar
• D. Visible White Light

Answer: (B)

When a CR image plate is read, the reader uses a laser to scan the plate. The imaging plate contains a photostimulable phosphor that stores energy from the X-ray exposure. The laser excites these trapped electrons, causing the stored energy to be released as photostimulated light, which is then detected and converted into the digital image. This precise, localized stimulation by a laser is essential for producing a clean, high-quality signal. Infrared light wouldn’t effectively stimulate the phosphor, sonar has no role in this optical process, and exposing the plate to visible white light would disturb or erase the stored signal rather than read it.
