With all other technical factors remaining constant, which of the following results from increasing amounts of filtration in the X-ray beam?

Increasing the amount of filtration in an X-ray beam has a direct effect on patient skin exposure. Filtration works by selectively absorbing lower energy X-rays from the primary beam that are more likely to be absorbed by the patient's skin. These lower energy photons contribute to patient dose but do not significantly contribute to the diagnostic quality of the image since they do not penetrate adequately through tissues.

By removing these less penetrating, low-energy photons, increasing filtration effectively reduces the overall radiation exposure to the skin, as the patient's body is only exposed to the higher energy photons that have a greater likelihood of generating useful image data. This means that while the total intensity of the X-ray beam may decrease, the quality and energy of the remaining beam are enhanced, helping to minimize unnecessary radiation to the patient.

In clinical practice, this reduction in skin exposure enhances patient safety and contributes to better radiation hygiene, while still allowing for an adequate quality of diagnostic information to be obtained from the imaging procedure.
