Question

a technologist is attempting to decrease the beam intensity and decrease the penetrability of the beam. the technologist should: increase source - to - image distance (sid) decrease milliamperage (ma) increase filtration decrease kilovoltage peak (kvp)

Explanation:

1. Increase SID: Inverse - square law applies. Increasing SID decreases beam intensity but doesn't directly decrease penetrability.
2. Decrease mA: Reduces the number of electrons hitting the target, decreasing beam intensity but doesn't change penetrability much.
3. Increase filtration: Removes low - energy photons, effectively increasing average energy and penetrability while reducing intensity.
4. Decrease kVp: Reduces the energy of the x - ray beam. Lower energy means decreased penetrability and also decreased beam intensity.

Answer:

Decrease kilovoltage peak (kVp)
