WebFeb 28, 2024 · Filtration reduces x-ray intensity, but not the maximum energy of the x-ray beam spectrum. The change in the shape of the beam spectrum with filtration is referred to as beam hardening. This is due to the loss of lower energy photons from a polychromatic …

WebJan 1, 1995 · To determine the total filtration of an X ray beam the user measures the half-value layer (HVL). The HVL is one of the parameters to be checked regularly in a Quality Assurance programme. WebAs the effective energy of an x-ray beam is increased (i.e., reducing the number of low energy x-rays by adding filtration), the penetrability is also increased.

Webthe average x-ray beam energy increases, meaning the x-ray beam has increased pene-trating power, the HVL also increases. In radiography, the two important deter-minants of x-ray beam quality are tube volt-age and beam filtration.
