Question

which technical adjustment would “harden” the x - ray beam? increased kilovoltage peak (kvp) decreased kilovoltage peak (kvp) adding filtration removing filtration

Explanation:

Hardening the x - ray beam means increasing the average energy of the x - ray photons in the beam. Adding filtration absorbs the lower - energy x - ray photons, leaving behind higher - energy photons and thus "hardening" the beam. Increasing kVp also increases the energy of the x - ray photons but adding filtration is a more direct way to harden the beam by selectively removing low - energy photons.

Answer:

C. Adding filtration
