The attenuation correction is usually applied to achieve count rate values independent from tissue densities.

The attenuation of radiation is a decrease in intensity as a result of interactions by transmission through matter. X-ray beams attenuate due to photon absorption by the material or scattering. Both effects are energy dependent. The probability of absorption or scattering is a function of the photon energy. The photoelectric absorption is much more energy dependent than the Compton scatter effect. See also Attenuation Correction, Linear Energy Transfer, Broad Beam and Ion Beam. Result Pages : |
