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...
Although Compton camera may has a great potential as next generation imaging modality comparing to SPECT and PET, its fully three-dimensional image reconstruction requires the considerable computational burden and the spatial resolution is suffered from the various physical phenomena arising during detection process. In this study, we investigated the accelerated statistical image reconstruction in...
Thallium bromide (TlBr) is of interest as a material for room temperature gamma ray spectroscopy due to its high density, high Z and wide bandgap. In addition, its cubic crystal structure and relatively low melting point facilitate crystal growth by melt techniques. Recent advances in material purification, crystal growth and device processing have led to mobility-lifetime products of electrons in...
