When using computed radiography, a smaller imaging plate may _____ than a larger imaging plate.

• A. Have better spatial resolution
• B. Have worse spatial resolution
• C. Take longer to process
• D. Produce more artifacts

Answer: (A)

Smaller imaging plates in computed radiography tend to give better spatial resolution because the light released from the phosphor layer has less distance to travel before it reaches the detector. That shorter path reduces lateral diffusion and blur, so edges and fine details are preserved more crisply. The readout system samples the image with a fixed pixel size, so a smaller plate effectively yields finer detail capture and less blurring of high-frequency information. Longer processing time isn’t driven by plate size, and artifacts aren’t inherently increased by using a smaller plate.
