The block diagram to depict the experimental setup is shown in Figure 3(b). Hence Positron emission tomography (PET) image denoising is a challenging task due to the presence of noise and low spatial resolution compared with other imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT). Coincidence data of the annihilation photons are acquired by the PET scanner. However, the main emphasis in PET is not on anatomical imaging, as e.g. Positron emission tomography (PET) is based on the physical properties of isotopes – radioactive forms of simple atoms (like hydrogen, oxygen, fluorine, etc. The article also discusses how competing electrical noise in the environment affects imaging, and why it is important to accurately detect photon timing and movement so the signal generated within the patient can be localized.
