Explanation:

Question 15

Voltage (kVp) in X - ray production: higher voltage increases beam quality (energy of photons) and also affects quantity (more high - energy photons, though quantity is more related to mAs, but voltage does impact both to some extent? Wait, no, actually, voltage (kVp) primarily affects beam quality (penetrating power, energy) and also affects quantity (number of photons) as higher kVp can lead to more bremsstrahlung photons. But the standard answer for this (in radiography) is that voltage affects both beam quantity and quality? Wait, no, let's recall: Beam quantity is the number of photons, beam quality is the energy of photons. kVp affects quality (higher kVp = higher energy, better quality) and also affects quantity (as higher kVp gives more photons, though mAs is the main controller of quantity). But the options: if we consider that voltage affects both, but maybe the intended answer is "both"? Wait, no, maybe I got it wrong. Wait, actually, in X - ray physics, kVp (voltage) affects beam quality (because it determines the maximum energy of photons, and the average energy) and also affects quantity (the number of photons, as higher kVp leads to more interactions that produce photons). So the correct option is "both".

Voltage (kVp) in X - ray: higher voltage means higher - energy photons, which have greater penetrating ability (penetrability). So voltage does affect penetrability. So the answer is "yes".

Answer:

both
