The Company

PETsys Electronics, S.A. builds up on its expertise to propose state-of-the art solutions for the PET detectors of the future, LIDAR and other applications. The technology offered today by PETsys Electronics, stems from more than ten years of R&D development involving a number of public and private partners: The R&D PET-Mammography Consortium (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.
