Overlooked emissions from exotic positronium atoms could improve medical scanners



Summary

Positronium, an exotic atom formed by an electron and positron, quickly annihilates, typically emitting two or three photons. However, physicists have discovered rare, overlooked emissions from positronium—specifically, low-energy gamma rays produced when an electron transitions between energy levels before annihilation.

These emissions could significantly improve medical imaging, like PET scans. By detecting these gamma rays, scanners could more precisely pinpoint the location of positron-emitting radiotracers used to diagnose diseases. This increased accuracy could lead to earlier and more accurate diagnoses, potentially revolutionizing medical imaging by providing finer details of internal body processes.
