WHY COMPTON SCATTERING IS IMPORTANT?

 According to the American Physical Society (APS) Physics, Compton scattering is important for :

• Radiobiology - the most probable interaction of gamma rays and high energy X-rays with atomic nuclei in living beings and is applied in radiation therapy 
• Material physics - used to probe the wave function of the electrons in matter.
• Gamma spectroscopy  - gives rise to the Compton edge, as it is possible for the gamma rays to scatter out of the detectors used.
• Diagnostic radiography -  relates to differences in the way photons are absorbed by various anatomic structures.

-    The number of photoelectric and Compton interactions is greater in hard tissues compared to soft tissues

-    More photons in the beam exit the patient after passing through soft tissue than through hard tissue. 

-    Thus, it allows a radiograph to provide a clear image of enamel, dentine, and bone and also, soft tissue.
