What impact does increased filtration have on radiation exposure during x-ray examinations?

Increased filtration in an x-ray examination setting is beneficial as it decreases radiation exposure to the patient. Filtration involves using materials (like aluminum) to remove low-energy, ineffective x-ray photons from the beam before it reaches the patient. These low-energy photons contribute to patient dose without enhancing image quality, as they are more likely to be absorbed by the body rather than pass through to create a clear image on the radiograph.

By filtering out these lower energy photons, the overall quality of the x-ray beam is improved, resulting in a more penetrating beam that can achieve the desired image quality while using a lower dose of radiation. Hence, with high filtration, the effective dose received by the patient is minimized, helping to reduce the risk of radiation-induced effects.

While equipment and other variables may influence how filtration is applied, the fundamental principle remains that increased filtration will lead to a reduction in overall radiation exposure during x-ray examinations.
