WebMar 6, 2016 · Beam attenuation occurs as a result of the photon interactions with the atomic structures that comprise the tissues. Two distinct processes occur during beam attenuation: absorption and scattering. Absorption As the energy of the primary x-ray beam is deposited within the atoms comprising the tissue, some x-ray photons are completely absorbed. WebPhotodisintegration occurs when a high-energy photon is absorbed by an atomic nucleus.
