When working with CR and DR, one must be aware that their response to scatter radiation is:

• A. Very sensitive
• B. Minimally sensitive
• C. Irrelevant
• D. Not considered

Answer: (A)

CR and DR detectors respond to scatter radiation with high sensitivity because they record a wide range of exposures, including scattered photons that don’t carry diagnostic information. Scatter adds a uniform fog to the image, which reduces contrast and can obscure fine details. Digital systems can adjust brightness and some contrast, but they can’t fully recover when scatter has degraded image quality, so the impact of scatter is more noticeable. That’s why you must actively minimize scatter—collimate well, use grids when appropriate, and choose techniques that limit scatter production.
