LSO: Ce scintillator ni LSO kristal ikozwe na cerium (Ce) ion.Kwiyongera kwa cerium bitezimbere imitekerereze ya LSO, bigatuma ikora neza cyane imishwarara ya ionizing.LSO: Ce scintillator ikoreshwa cyane muri scaneri ya Positron Emission Tomography (PET), igikoresho cyerekana amashusho yubuvuzi gikoreshwa mugupima no kuvura indwara zitandukanye nka kanseri, Alzheimer nizindi ndwara zifata ubwonko.Muri scaneri ya PET, LSO: Ce scintillator ikoreshwa mugutahura fotone yasohowe na radiotracers isohora positron (nka F-18) yinjiye mumurwayi.Izi radiotracers zangirika beta, zisohora fotone ebyiri muburyo butandukanye.Fotone ibika ingufu muri LSO: Ce kristal, itanga urumuri rwa scintillation ifatwa kandi ikagaragazwa numuyoboro wa Photomultiplier (PMT).PMT isoma ikimenyetso cya scintillation ikayihindura mumibare yamakuru, itunganywa kugirango itange ishusho yikwirakwizwa rya radiotracer mumubiri.LSO: Ce scintillator ikoreshwa no mubindi bikorwa bisaba imashini ikora cyane, nka X-ray yerekana amashusho, fiziki ya kirimbuzi, fiziki y’ingufu nyinshi, hamwe na dosiye yimirasire.
LSO, cyangwa isasu rya scintillation oxyde, nibikoresho bisanzwe bikoreshwa mugutahura imirasire no gukoresha amashusho.Ni kristu ya scintillation yaka iyo ihuye nimirasire ya ionizing nka imirasire ya gamma cyangwa X-X.Umucyo uhita umenyekana ugahinduka ibimenyetso byamashanyarazi, bishobora gukoreshwa mugukora amashusho cyangwa kumenya imirasire ihari.LSO ifite ibyiza byinshi kurenza ibindi bikoresho bya scintillation, harimo gusohora urumuri rwinshi, igihe cyangirika vuba, gukemura neza kwingufu, nyuma ya nyuma, hamwe nubucucike bwinshi.Nkigisubizo, kristu ya LSO ikoreshwa mubikoresho byerekana amashusho yubuvuzi nka PET scaneri, ndetse no mubikorwa byumutekano no gukurikirana ibidukikije.
