Abstract

This work reports on the characterization of TlBr detectors for use in nuclear medicine. Several different detectors have been used to assess the potential performance of the material. A 12 mm thick detector with a Frisch collar has been used to achieve an energy resolution of 3.5% at 511 keV and 2.3% at 662 keV. A 0.4 mm thick detector biased at 200 V has been operated in coincidence with an LSO crystal coupled to a PMT and a timing resolution of 24 ns FWHM has been obtained by gating the energy of the events. A strip TlBr detector with 0.4 mm width strips and 0.1 mm interstrip separation has been used to measure the intrinsic spatial resolution to the level of 1 mm (a result limited by the setup geometry). The results show promising results of TlBr detectors for nuclear medicine applications.
