CaLIPSO, QUYOS
CaLIPSO is a medical imaging project aiming at a breakthrough in high-spatial-resolution Positron Emission Tomography (PET). The CaLIPSO concept for the detection of 511 keV gamma rays is based on the precise 3D localisation of the photoelectron in an organometallic liquid, associated with ultra fast electronics. This detector R&D activity is on-going at IRFU since 2009, with very promising results.
