Also known as coherent scattering or classical scattering, Thompson scattering is one of the four fundamental interactions that transpire when photons (x-rays) collide with atoms. In this scenario, a low-energy x-ray photon collides with an inner-orbital electron, but its limited energy is insufficient to dislodge the electron. Instead, the electron can absorb the photon, resulting in the vibration of the photon and the generation of an electromagnetic wave in a different direction. It is worth noting that this type of interaction occurs at energy levels below the range typically employed in clinical radiology.
