Which three of the following are types of filtration found in the x-ray imaging system?

Filtration in an x-ray imaging system serves a critical role in enhancing image quality and minimizing patient dose by selectively absorbing low-energy x-rays that do not contribute to the diagnostic image. The two main types of filtration are inherent and added filtration.

Inherent filtration is the filtration that occurs naturally within the x-ray tube and its components. It is typically comprised of the glass or metal envelope of the x-ray tube and any other materials that the x-ray beam passes through before it exits the tube.

Added filtration refers to any additional filtration material placed in the path of the x-ray beam. This usually involves materials such as aluminum, which is specifically chosen for its ability to absorb low-energy radiation while allowing higher-energy x-rays to pass through.

Aluminum is frequently used in modern x-ray machines to provide added filtration because it is effective at reducing patient exposure and improving the quality of the x-ray beam. Thus, when referring to types of filtration in x-ray imaging systems, it is accurate to identify both inherent and added filtration as integral components, where aluminum serves as the common material for added filtration.

While lead can be utilized in other areas of radiation protection, such as in shielding, it is not typically classified as a type of filtration in this context. Using
