Higher kVp would do what to the penetration?

Higher kVp would do what to the penetration?

• A. Decrease penetration
• B. No change
• C. Increase penetration
• D. Decrease contrast

Answer: (C)

Raising kVp increases the energy (quality) of the x-ray photons. With higher energy, photons are more likely to pass through tissues rather than being absorbed, so the beam penetrates more effectively. In other words, higher kVp makes the beam more penetrating. Keep in mind this comes with a trade-off: image contrast tends to decrease as penetration increases due to more scatter and transmission across tissues.
