How does patient size influence mAs and kVp selection?

How does patient size influence mAs and kVp selection?

• A. Smaller patients require higher mA and kVp to compensate for less attenuation.
• B. Patient size has no impact on exposure parameters.
• C. Larger patients often require higher mA or longer exposure, and possibly higher kVp to maintain penetration with manageable dose.
• D. Always use the same exposure for all patients.

Answer: (C)
