Solution
The correct option is C PET In a material medium, when a positron meets an electron both the particles annihilate leading to the emission of two gamma ray photons. This process forms the basis of an important diagnostic procedure called PET. Positron emission tomography (PET) is a nuclear medicine medical imaging technique which produces a three dimensional image area map of functional process in the body. The positron annihilates with an electron producing a pair of annihilation photons (gamma rays) moving in opposite direction.
