LSO:Ce Scintillator, Lso Crystal, Lso Scintillator, Lso scintillation crystal

incazelo emfushane:

LSO: Ce (Lu₂SiO₅:Ce) i-crystal ingolunye uhlobo lwezinto ze-inorganic scintillation ezinempahla ethuthukisiwe okuhlanganisa ukuphuma kokukhanya okuphezulu, isikhathi sokubola esifushane, ukumelana okuhle kakhulu nomsakazo, ukuminyana okuphezulu, inombolo ye-athomu esebenza kahle kakhulu, ukutholwa okuphezulu kokusebenza kahle ngokumelene ne-gamma ray, i-non-hygroscopic kanye nokuzinza njll.

Isingeniso Somkhiqizo

I-LSO:Ce scintillator iyikristalu ye-LSO ehlanganiswe nama-ion e-cerium (Ce).Ukwengezwa kwe-cerium kuthuthukisa izakhiwo ze-scintillation ze-LSO, okwenza kube umtshina osebenza kahle wemisebe ye-ionizing.I-LSO:Ama-Ce scintillator asetshenziswa kakhulu kuzikena ze-Positron Emission Tomography (PET), ithuluzi lokuthwebula lezokwelashwa elisetshenziselwa ukuxilonga nokwelapha izifo ezahlukahlukene ezinjengomdlavuza, i-Alzheimer's nezinye iziphazamiso zemizwa.Kuma-PET scanners, ama-LSO:Ce scintillator asetshenziselwa ukuthola ama-photon akhishwa ama-positron-emitting radiotracers (afana ne-F-18) ethulwa esigulini.Lawa ma-radiotracer athola ukubola kwe-beta, akhiphe ama-photon amabili ngezindlela ezihlukile.Ama-Photons afaka amandla ngaphakathi kwe-LSO:Ce crystal, ekhiqiza ukukhanya kwe-scintillation okushuthwa futhi kutholwe ngeshubhu le-photomultiplier (PMT).I-PMT ifunda isignali ye-scintillation bese iyiguqulela kudatha yedijithali, ecutshungulwa ukukhiqiza isithombe sokusatshalaliswa kwe-radiotracer emzimbeni.I-LSO:Ama-Ce scintillator aphinde asetshenziswe kwezinye izinhlelo zokusebenza ezidinga izitholi ze-scintillation ezisebenza kahle, ezifana ne-X-ray imaging, i-nuclear physics, i-high-energy physics, kanye ne-radiation dosimetry.

I-LSO, noma i-lead scintillation oxide, iyinto evame ukusetshenziswa ekutholeni imisebe nasekusetshenzisweni kwezithombe.Kuyikristalu ye-scintillation ekhazimulayo lapho evezwe emisebeni ye-ionizing njengemisebe ye-gamma noma ama-X ray.Ukukhanya kube sekutholwa futhi kuguqulelwe kumasignali kagesi, angasetshenziswa ukwenza izithombe noma ukubona ukuba khona kwemisebe.I-LSO inezinzuzo ezimbalwa ngaphezu kwezinye izinto zokucwenga, okuhlanganisa ukuphuma kokukhanya okuphezulu, isikhathi sokubola okusheshayo, ukulungiswa kwamandla okuhle kakhulu, ukukhanya okungemuva okuphansi, nokuminyana okuphezulu.Ngenxa yalokho, amakristalu e-LSO avame ukusetshenziswa emishinini yokuthwebula yezokwelapha efana nezikena ze-PET, kanye nasekuvikelekeni nasekuqashweni kwemvelo.
