The total filtration of the useful x-ray beam is defined as the combination of both added and inherent filtration. Inherent filtration refers to the materials that are part of the x-ray tube and its housing, such as the glass or metal envelope of the tube and any other components that contribute to the filtration of the beam. This type of filtration occurs naturally as x-rays pass through these materials before reaching the patient.

Added filtration, on the other hand, consists of additional materials placed in the x-ray beam path to further reduce the number of low-energy photons that do not contribute to the image but can increase patient dose. These are typically metal filters that are placed in front of the x-ray tube.

By combining both inherent and added filtration, the total filtration allows for a more efficient and safer delivery of x-ray beams by removing unnecessary low-energy photons, thereby improving image quality and reducing patient exposure. This understanding is critical for ensuring optimal patient care and effective use of fluoroscopic equipment.
