Abstract. Several newly developed scintillators, namely Lu2SiO5:Ce, LuAlO3:Ce, and LaBr3:Ce, have attractive properties for nuclear medical imaging. These properties include excellent energy resolution, high light output, short decay lifetime, and reasonably high density and effective atomic number. This presentation compares the properties of these materials and analyzes how well they meet...

23. Cherenkov radiation in medical imaging

Dr P. Lecoq

Abstract: Charged particles traversing a medium at a speed exceeding the speed of light in this medium will emit Cerenkov radiation. In biological soft tissues the contents of water ranges from 70% in the brain to 90% in lungs. With the index of refraction of water (1.33) the Cerenkov energy threshold is 260 KeV. Scintillating crystals used as radiation detectors in SPECT and PET scanners...
