Iftiimin Muhiim ah - LSO2 (Ce) Crystal oo loogu talagalay Xasaasiyadda Muuqaalka ee La Kordhiyay
Soo bandhig sanduuqa wafer-ka
Kilaasteena LSO(Ce) waxay matalaysaa heerka ugu sarreeya ee tiknoolajiyada walxaha scintillation, iyadoo bixinaysa waxqabad heer sare ah oo ku saabsan codsiyo kala duwan. Iyadoo lagu farsameeyay saxnaan iyo khibrad, kiristaalkan waxaa lagu dahaadhay cerium (Ce) si loo xoojiyo hufnaanta wax soo saarka iftiinka iyo jawaab celinta muuqaalka.
Crystal-ka LSO (Ce) wuxuu ku faanaa xallinta tamarta iyo astaamaha waqtiga oo aad u sarreeya, taasoo ka dhigaysa doorasho ku habboon sawir-qaadista qiiqa positron (PET), sawir-qaadista gamma-ray, iyo codsiyada kale ee sawir-qaadista caafimaadka iyo ogaanshaha shucaaca. Iftiinkeeda sare iyo waqtiga qudhunka degdega ah waxay hubiyaan ogaanshaha saxda ah oo lagu kalsoonaan karo ee shucaaca gamma iyo shucaaca kale ee ionizing.
Iyada oo leh waxqabadkeeda iyo isku hallaynteeda heer sare ah, kiristaalkayaga LSO (Ce) wuxuu dejiyaa heer cusub oo loogu talagalay agabka wax lagu shido, taasoo suurtogalinaysa horumarinta cilmi-baarista sayniska, baaritaanka caafimaadka, iyo amniga waddanka. La kulan xasaasiyad iyo saxnaan aan la barbar dhigi karin oo leh kiristaalkayaga LSO (Ce), taasoo horseedaysa hal-abuurka iyo daahfurka qaybaha kala duwan.
