SINGLE CRYSTAL CYLINDRICAL POSITRON TOMOGRAPH

POSITRON EMISSION TOMOGRAPHY HAS BEEN SHOWN TO BE USEFUL IN THE DIAGNOSIS OF BOTH CARDIAC AND NEUROLOGIC DISORDERS. THEGOAL OF THIS PROJECT IS THE DEVLOPMENT OF A POSITRON EMISS- SION TOMOGRAPH, WHICH DUE TO ITS SIMPLE DESIGN, WILL BE MORESUITABLE FOR ROUTINE CLO RESEARCH ORIENTED POSITRON TOMOGRAPHS. THE SINGLE CRYSTAL POSITRON TOMOGHRAPH WILL HAVE A CYLIN- DRICAL SCINTILLATION DETECTOR TO WHICH APPROXIMATELY 160 PHOTOMULTIPLIERS ARE COUPLED. IT WILL HAVE A DIAMETER OF 60CM WITH AN AXIAL FIELD OF VIEW OF APPROXIMATELY 12 CM, THUS MAKING IT SUITABLE FOR BRAIN IMAGING. PHASE I OF THE PROPOSAL CONSISTS OF A FEASIBILITY STUDY WHICH WILL HOPEFULLY LEAD TO THE CONSTRUCTION OF A COMPLETE SCANNER AS PART OF PHASE II.
