I-Illuminated Essence – Cutting-Edge LSO(Ce) Crystal Yokuzwela Okuthuthukisiwe KweSpectral

I-Illuminated Essence – Cutting-Edge LSO(Ce) Crystal yesithombe esifakiwe esithuthukisiwe se-Spectral Sensitivity

Incazelo emfushane:

Sethula i-“Illuminated Essence,” umkhiqizo ophambili ohlanganisa ubuchwepheshe bekristalu be-LSO(Ce). Idizayinelwe ukuguqula ukuzwela kwe-spectral, inikeza ukusebenza okungenakuqhathaniswa kuwo wonke umcabango wezokwelapha, ucwaningo lwe-nuclear physics, nezinhlelo zokusebenza zokuphepha kwezwe. Ngobunjiniyela obucophelelayo kanye nokukhiqiza okuthuthukile, iletha ukukhanya okuyingqayizivele namandla okubona anembe, ibeka izindinganiso ezintsha ekusungulweni kwezinto ezintsha ze-scintillation. I-abstract yomkhiqizo wethu igqamisa izimfanelo eziyingqayizivele nezinhlelo zokusebenza eziguquguqukayo, okubonisa amandla ayo okuthuthukisa imikhakha ehlukahlukene encike kubuchwepheshe bekristalu obusebenza kakhulu.

Ukwethulwa kwebhokisi le-wafer

Ikristalu yethu ye-LSO(Ce) imele isiqongo sobuchwepheshe bezinto ezibonakalayo ze-scintillation, enikeza ukusebenza okuyingqayizivele ezinhlobonhlobo zezinhlelo zokusebenza. Iklanywe ngokunemba nobungcweti, le crystal ifakwe i-cerium (Ce) ukuze ithuthukise ukusebenza kahle kwayo kokuphuma kokukhanya kanye nokusabela kwe-spectral.

Ikristalu ye-LSO(Ce) iziqhayisa ngokulungiswa kwamandla okuphakeme kanye nezici zesikhathi, okuyenza ibe yinketho ekahle ye-positron emission tomography (PET), i-gamma-ray spectroscopy, nezinye izinhlelo zokusebenza ze-imaging yezokwelapha kanye nokutholwa kwemisebe. Isivuno sayo sokukhanya okuphezulu nesikhathi sokubola ngokushesha kuqinisekisa ukutholakala okunembile nokuthembekile kwemisebe ye-gamma neminye imisebe ye-ionizing.

Ngokusebenza kwayo okuvelele nokwethembeka, ikristalu yethu ye-LSO(Ce) isetha indinganiso entsha yezinto zokwakha ze-scintillation, evumela intuthuko ocwaningweni lwesayensi, ukuxilonga ngezokwelapha, kanye nokuphepha kwezwe. Izwa ukuzwela okungenakuqhathaniswa nokunemba ngekristalu yethu ye-LSO(Ce), ukushayela ukuqanjwa nokutholakala emikhakheni ehlukahlukene.
