Abstract

The easyPET concept described here aims to reduce complexity and cost of preclinical Positron Emission Tomography (PET) scanners. The system, original in its principle and realisation, is based on a single pair of detectors and a rotating mechanism with two degrees of freedom reproducing the functionalities of an entire PET ring. The characterisation of a 2D imaging prototype, realised to assess the easyPET concept, is presented in this paper. In particular, a spatial resolution of 1±0.1. mm and a sensitivity of 0.1% with an energy threshold of 80. keV have been measured. These encouraging results, compared to the performances of commercial preclinical PET, motivate the feasibility study of a 3D system.
