Positron Emission Tomography (PET) is a key technique in the medical imaging area, which allows for diagnosing organism functions and tracking tumour changes. In PET measurement, the patient is injected with a radiotracer containing a large number of metastable atoms of radionuclide that emits positrons. As a result of positron annihilation, two photons travelling almost in opposite directions are produced...
