I have already included the introduction for my paper. This paper should be mostly about how Positron Emission Tomography is related to Physics such as equations used in physics, the facts about how it functions in relation to gamma rays, and more. It also needs to include the sub points I have mentioned in the intro including the history of the PET, what it actually is, the current uses, and future outlook as to where this type of technology could lead the medical field. The paper needs to have 4 peer-reviewed sources.
