LSO:Ce scintillator bụ kristal LSO nke nwere cerium (Ce) nwere ion.Mgbakwunye nke cerium na-eme ka njirimara scintillation nke LSO dịkwuo mma, na-eme ka ọ bụrụ ihe na-achọpụta nke ọma nke radieshon ionizing.LSO:Ce scintilators na-eji ọtụtụ ebe na Positron Emission Tomography (PET) scanners, a ọgwụ onyunyo ngwá ọrụ e ji achọpụta na ọgwụgwọ dị iche iche ọrịa dị ka cancer, Alzheimer's na ndị ọzọ na akwara ozi ọrịa.Na nyocha PET, LSO:Ce scintilators na-eji achọpụta foton ndị rediotracers positron-emitting (dị ka F-18) na-ewepụta n'ime onye ọrịa.Ndị na-ahụ maka redio a na-enweta ire ere beta, na-ahapụ foton abụọ n'akụkụ nke ọzọ.Photons na-etinye ike n'ime LSO:Ce crystal, na-emepụta ìhè scintillation nke tube fotomultiplier (PMT) na-ejide ma chọpụta.PMT na-agụ akara ngosi scintillation ma gbanwee ya na data dijitalụ, nke a na-ahazi iji mepụta ihe oyiyi nke nkesa rediotracer n'ime ahụ.LSO: A na-ejikwa scintilators Ce na ngwa ndị ọzọ na-achọ ihe nchọpụta scintillation dị elu, dị ka imaging X-ray, physics nuklia, physics ike dị elu, na dosimetry radieshon.

LSO, ma ọ bụ lead scintillation oxide, bụ ihe a na-ejikarị na nchọpụta radieshon na ngwa onyonyo.Ọ bụ kristal scintillation nke na-egbuke egbuke mgbe ekpughere ya na radieshon ionizing dị ka ụzarị gamma ma ọ bụ X-ray.A na-achọpụtazi ọkụ ahụ wee gbanwee ka ọ bụrụ akara ọkụ eletrik, nke enwere ike iji mee ihe oyiyi ma ọ bụ chọpụta ọnụnọ nke radieshon.LSO nwere ọtụtụ uru karịa ihe scintillation ndị ọzọ, gụnyere mmepụta ọkụ dị elu, oge ire ere ngwa ngwa, mkpebi ike dị mma, obere ọkụ ọkụ, na njupụta dị elu.N'ihi nke a, a na-ejikarị kristal LSO eme ihe na ngwa ihe onyonyo ahụike dịka nyocha PET, yana nchekwa na ngwa nlekota gburugburu ebe obibi.
