In Computed Radiography, the phosphor plate is scanned by what device?

• A. X-ray
• B. LED
• C. Laser
• D. CCD

Answer: (C)

In Computed Radiography, the plate stores the image as trapped energy after exposure. To read it, a reader uses a finely focused laser that scans the plate line by line. The laser stimulates the stored energy, releasing photostimulated luminescence which is then captured by a detector and converted into a digital image. The laser provides precise, high-resolution stimulation essential for accurate readout. X-ray exposure is what creates the image, not the reading process, and while detectors collect the emitted light, the scanning mechanism itself is the laser.
