Question

3 multiple choice 1 point beam filtration does what to patient dose? it has no effect on patient dose. it increases patient dose. it decreases patient dose. it increases patient dose by the square of the filter thickness. 4 multiple choice 1 point beam filtration affects patient dose by removing high - energy photons. removing low - energy photons. increasing beam heterogeneity. increasing entrance skin dose (ese).

Explanation:

Beam filtration removes low - energy photons which contribute more to skin dose and less to the diagnostic image. By removing them, the overall patient dose is decreased. Also, beam filtration is used to make the beam more homogeneous by preferentially removing low - energy photons.

Answer:

1. C. It decreases patient dose.
2. B. removing low - energy photons.
