Question: 1 / 400

How does filtration affect the low-energy portion of the X-ray beam?

Increases the low-energy portion

Decreases the low-energy portion

Filtration is an essential process in radiography that primarily impacts the quality and characteristics of the X-ray beam. When filtration is applied, it selectively removes low-energy photons from the X-ray beam.

Low-energy photons are less penetrating and primarily contribute to patient dose without enhancing image quality, as they do not reach the imaging receptor effectively. By filtering out these lower-energy photons, the overall energy of the beam is increased, while also improving image contrast and reducing patient exposure to unnecessary radiation.

Thus, the appropriate choice regarding how filtration affects the low-energy portion of the X-ray beam is that it decreases this low-energy portion. This process ultimately results in a higher quality X-ray beam that is better suited for diagnostic imaging.
