Which receptor offers simple exposure?

• A. CCD/CMOS
• B. PSP
• C. Both
• D. Neither

Answer: (B)

Exposure latitude and dynamic range drive how forgiving a receptor is to exposure errors. PSP plates used in computed radiography have a wide exposure latitude, so a broad range of exposure levels still yields usable diagnostic images. This makes the exposure process simpler and more forgiving in practice. In contrast, CCD/CMOS direct digital detectors have a narrower dynamic range, so they’re more sensitive to over- or underexposure and require more precise technique to avoid noise or loss of detail. Because of that greater sensitivity to exposure, PSP is the better choice for simple exposure.
