The LPET OTech project explores a new paradigm of PET-imaging technology exploiting the rich detection framework provided by the novel LiquidO technology for e+ annihilation identification and high-precision characterisation, as inherited from neutrino detection.
The main features of the LPET-OTech system are:
- multi-γ annihilation detection (≥2), so conventional β+ and γ-β+ lead, respectively, to a single and coincidence annihilation pattern.
- positronium exploitation for parametric imaging, including the exploitation of ortho-positronium.
- high duty-cycle detection since the LiquidO’s detection mechanism is paced by the speed of light in the medium and reinforced by pulse-shape discrimination handles for possible pile-up handling.
- high precision (few mm) 3D vertex measurements of the 1st-Compton interaction, as opposed to the photo-electric effect capture, including the additional constraints from
- energy flow LiquidO’s pattern
- full Compton even reconstruction per γ detected — Compton camera equivalent
The main goal of the LPET OTech project is the design and experimental demonstration of the system for PET imaging in a progressive staged approach.
