Question

which of the following would decrease patient exposure and increase the quality of the x - ray beam?
increased distance
increased filtration
decreased distance
decreased filtration

Explanation:

Increased filtration removes low - energy photons from the x - ray beam. This reduces patient exposure as the low - energy photons are not useful for imaging and contribute to unnecessary radiation dose. Also, it increases the quality of the x - ray beam by making it more homogeneous and penetrating. Increasing distance reduces exposure but has less impact on beam quality compared to filtration. Decreasing distance increases exposure and decreasing filtration increases the number of low - energy photons, reducing beam quality and increasing exposure.

Answer:

Increased filtration
