Essence Illuminated – Icha-Edge LSO(Ce) kristal maka Mmelite Spectral Sensitivity

Nkọwa dị mkpirikpi:

Na-ewebata “Illuminated Essence,” ngwaahịa dị oke ọnụ nke na-egosipụta teknụzụ kristal LSO(Ce). Emebere ya ka ọ gbanwee mmetụta pụrụ iche, na-enye arụmọrụ enweghị atụ n'ofe onyonyo ahụike, nyocha physics nuklia na ngwa nchekwa ala nna. Site na injinia nke ọma na imepụta ihe dị elu, na-ewepụta ìhè pụrụ iche na ike nchọpụta ziri ezi, na-esetịpụ ụkpụrụ ọhụrụ na mmepụta ihe ọhụrụ scintillation. Ngwakọta ngwaahịa anyị na-egosipụta njirimara pụrụ iche yana ngwa dịgasị iche iche, na-egosipụta ikike ọ nwere ịkwalite ọganihu na mpaghara dị iche iche dabere na teknụzụ kristal na-arụ ọrụ dị elu.

kristal LSO (Ce) anyị na-anọchite anya teknụzụ akụrụngwa scintillation, na-enye arụmọrụ pụrụ iche n'ọtụtụ ngwa. N'ịbụ nke ejiri nkenke na nka rụọ ọrụ, kristal a na-etinye cerium (Ce) iji kwalite nrụpụta ọkụ ya na nzaghachi ọpụrụiche.

kristal LSO(Ce) na-anya isi mkpebi ike dị elu na njirimara oge, na-eme ka ọ bụrụ nhọrọ dị mma maka tomography positron emission (PET), spectroscopy gamma-ray, yana onyonyo ahụike na ngwa nchọpụta radieshon ndị ọzọ. Mkpụrụ ọkụ ya dị elu na oge ire ere ngwa ngwa na-eme ka nchọpụta gamma na ụzarị ionizing ndị ọzọ dị mma na nke a pụrụ ịdabere na ya.

Site na arụmọrụ ya pụtara ìhè na ntụkwasị obi, LSO (Ce) kristal na-esetịpụ ụkpụrụ ọhụrụ maka ihe scintillation, na-eme ka ọganihu na nyocha sayensị, nchọpụta ahụike, na nchekwa ala nna. Nweta mmetụta na-enweghị atụ na nkenke na kristal LSO (Ce) anyị, ihe ọhụrụ na-akwọ ụgbọala na nchọpụta n'ọhịa dị iche iche.
