Scientific Publications (Patents, Papers and Slides)
PETsys technology was developed since 2003 based in APDs (Avalanche Photo Diodes), as photo sensors, and it is being updated since 2011 using SiPM (Silicon Photomultipliers).
For the current stage of our technology (SiPM), these are the relevant patents:
On SiPM readout apparatus (ASIC):
On "Scintillator array for gamma ray or X-ray detection with Depth of Interaction information", based on work done with CERN as a partner:
The first patents obtained (for our technology based in APDs-Avalanche Photo Diodes) were the following :
