Positron emission tomography is widely used in medical physics for the reconstruction of the distribution of radionuclei molecules for analyzing regional physiological functions. The existing maximum a posteriori reconstruction methodologies produce artifacts such as oversmoothing and streaking. In this letter, the author proposes a potential function based on fuzzy-median filter for noise-free image reconstruction. The reconstruction methodology is therefore very useful for obtaining artifact-free reconstruction of biomedical specimens.
