Abstract
Combined PET-CT scanners are becoming standard for clinical PET imaging. The development of a combined PET-MR scanner poses greater technological challenges. A prototype small animal MR compatible PET scanner has previously been designed, constructed and evaluated in collaboration with UCLA School of Medicine. Final tests have now been carried out to validate the design of a new system that addresses the limitations of the prototype. The new scanner will consist of one ring of 416 LSO crystals (2x3x5 mm) arranged in 4 layers with an inner diameter of 7.5 cm and will be used for molecular imaging studies with mice and small rats. Each crystal is coupled to 1 of 8 multi-channel photomultiplier tubes, situated away from the MR scanner, via 3 m long optical fibres. Experiments have been performed to optimize all aspects of the system. Results of the validation studies and the configuration of the new system will be described. The system is now under construction and we predict it will have a uniform spatial resolution of
