Inherent filtration in radiography refers to filtration that is:

Inherent filtration in radiography refers to the filtration that is built into the x-ray tube itself as part of its design. This type of filtration is primarily due to the materials that make up the tube, such as the glass or metal enclosure, which absorb low-energy photons that do not contribute to image formation and instead increase patient dose.

The inherent filtration effectively helps to improve the quality of the x-ray beam by removing these less penetrating rays, allowing for a higher average energy and reducing the potential for unnecessary radiation exposure. Understanding the role of inherent filtration is crucial for radiologic technologists, as it ensures that the x-ray imaging process is both effective and safe for patients.
