抄録

Thallium bromide (TlBr) is a candidate material for room-temperature semiconductor gamma-ray detectors with high detection efficiency and energy resolution. By adopting a pixelated detector configuration, a TlBr detector can determine not only the deposition energy but also the 3D positions of interactions between gamma-ray photons and the detector medium. A Compton imager, which can measure the directional distribution of incident gamma rays based on Compton scattering kinetics, can be realized by using the information of deposition energies and interaction positions in the gamma-ray detector. In this study, we demonstrated Compton imaging using a pixelated TlBr semiconductor detector.
