Positronium is the simplest bound state, built of an electron and a positron. Studies of
positronium in vacuum and its decays in medium tell us about quantum electrodynamics …

Compton imaging exploits inelastic scattering, known as Compton scattering, using a
Compton camera consisting of a scatterer detector in the front layer and an absorber …

In vivo assessment of cancer and precise location of altered tissues at initial stages of
molecular disorders are important diagnostic challenges. Positronium is copiously formed in …

Charged lepton system symmetry under combined charge, parity, and time-reversal
transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic …

The purpose of the presented research is estimation of the performance characteristics of
the economic total-body Jagiellonian-PET system (TB-J-PET) constructed from plastic …

Positronium is abundantly produced within the molecular voids of a patient's body during
positron emission tomography (PET). Its properties dynamically respond to the submolecular …

Pioneering investigations on the usage of positron-emission-tomography (PET) for the
monitoring of ion beam therapy with light (protons, helium) and heavier (stable and …

Abstract Positronium (Ps), a hydrogen-like atom consisting of a positron and an electron, is
efficiently formed in the human body during positron emission tomography (PET) …

In this review article, we present arguments demonstrating that the advent of high sensitivity
total-body PET systems and the invention of the method of positronium imaging, open …

Background Positron emission tomography (PET) traditionally uses coincident annihilation
photons emitted from a positron interacting with an electron to localize cancer within the …
