Positron detection in silica monoliths for miniaturised quality control of PET radiotracers†
Abstract
We demonstrate the use of the miniaturised Medipix positron sensor for detection of the clinical PET radiotracer, [68Ga]gallium-citrate, on a silica-based monolith, towards microfluidic quality control. The system achieved a far superior signal-to-noise ratio compared to conventional sodium iodide-based radio-HPLC detection and allowed real-time visualisation of positrons in the monolith.
