First positronium imaging of the human brain using a multi-photon j-pet scanner

The Jagiellonian Positron Emission Tomograph (J-PET) is the first multi-photon PET scanner capable of measuring momentum vectors and polarization of photons originating from the decays of positronium. J-PET enables imaging of positronium properties in living organisms, the study of discrete symmetries in positronium decays, and studies of the degree of quantum entanglement of photons from electron-positron annihilations. We will present the first-ever images of the properties of positronium in humans [1,2,3], the most accurate results to date of P, T, CP, and CPT symmetry tests in the decays of positronium atoms [4,5], and the first observation of non-maximal entanglement of photons from positronium annihilation in matter [6].
