WebThe LYSO crystals have intrinsic radioactivity due to the Lu-176 isotope. 176 Lu is a beta-emitter primarily decaying to an excited state of 176 Hf. This isotope emits gamma photons with energies of 307 keV, 202 keV, and 88 keV [ 12 ]. The crystal’s self-emission causes the crystal to be excited and produce scintillation light. WebThe results suggest that optically coupling together scintillators with a high refractive index adhesive, in combination with an NN algorithm, reduces edge-effects and makes it possible to build scanners with almost no gaps in between detectors.
