A Handheld beta(+) Probe for Intra-Operative Detection of Radiotracers

A handheld probe for direct positron detection based on scintillators coupled to silicon photomultipliers (SiPMs) is presented in this paper. The battery-powered system is optimised for intra-operative use. It is fully sterilisable and wirelessly connected to a PC running a graphical user interface. Successful pilot clinical trials have shown the use in oncological surgery.
