Compton Effect (CE)

back (1K)       next (1K)

  • In the Compton effect, the incident photon interacts with an orbital electron, ejecting it from the atom.

  • At the point of interaction, a new photon is generated and re-irradiated in a direction different from the incident angle.

  • The photon can then interact with other atoms until photon energy is dissipated.

  • This is the most important interaction mechanism in tissue-like materials.

  • The Compton effect is also called inelastic scattering.
