In computed radiography, which indicator shows the dose delivered to the photostimulable phosphor plate?

• A. Dose area product
• B. Exposure indicator number
• C. Time
• D. Kilovoltage

Answer: (B)

In computed radiography, the exposure indicator number is the readout that shows how much radiation the photostimulable phosphor plate actually absorbed. The plate stores energy in proportion to exposure, and when it’s read out, the amount of light emitted correlates with that stored energy, giving you an exposure indicator. This number helps assess whether the plate received an appropriate dose and guides technique adjustments for future exams. Dose area product reflects the patient’s dose over the beam area and isn’t a readout of plate exposure; time and kilovoltage influence exposure but aren’t direct indicators of the plate’s dose.
