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 x - rays, reducing patient exposure and increasing the average energy (quality) of the x - ray beam. Increased distance also reduces exposure but has less impact on beam quality compared to filtration. Decreased distance increases exposure and decreased filtration would increase the number of low - energy x - rays, reducing beam quality.

Answer:

Increased filtration
