WebJul 28, 2016 · The gamma rays collide with electrons in the formation, giving off energy and scattering in a process known as Compton Scattering. The number of such collisions is directly related to the number of electrons in the formation. In low-density formations, more of these scattered gamma rays are able to reach the detector than in formations of ... WebGamma rays called annihilation photons are created when positrons collide with electrons near the decay event. The scanner then detects the annihilation photons, which arrive at the detectors in coincidence at 180 degrees apart from one another. A computer analyzes those gamma rays and uses the information to create an image map of the organ or ...
