摘要: We report on the characterization of 2 mm thick CdTe diode detector with Schottky contacts to be employed in a novel conceptual design PET scanner. Results at -8°C an applied bias voltage -1000 V/mm show 1.2% FWHM energy resolution 511 keV. Coincidence time has been measured by triggering preamplifier output signal improve timing detector. same and temperature conditions 6 ns minimum acceptance 500 These results that pixelated is excellent candidate for development next generation nuclear medical imaging devices such as PET, Compton gamma cameras, especially PET-MRI hybrid systems when used magnetic field immune configuration.
