Beam filtration does what to patient dose?
A)It has no effect on patient dose.
B)It increases patient dose.
C)It decreases patient dose.
D)It increases patient dose by the square of the filter thickness.

Quizplus · Accepted Answer

Beam filtration decreases patient dose by removing low-energy photons from the beam before it reaches the patient. This reduces the amount of scatter and increases the average energy of the photons that do reach the patient, resulting in a lower dose delivered to the patient.
