(involving approximately 40 people from 10 research institutions), and assembled in 2003, was responsible for the technological solutions (i.e. electronics, mechanics, image reconstruction) that gave birth to two Clear-PEM prototypes. These systems allow unmatched image resolution and sensitivity for breast imaging using PET tracers. PETsys - Medical PET Imaging Systems, S.A. was incorporated in 2008 to bring the Clear-PEM scanner technology to market. PETsys Electronics, S.A., setup by PETsys Systems SA in 2013, builds up on this expertise to propose state-of-the art solutions for the PET detectors of the future.
