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

Kufotokozera mwachidule:

LSO: Ce (Lu₂SiO₅:Ce) crystal ndi mtundu wina wazinthu zopangira scintillation zokhala ndi zinthu zapamwamba kuphatikiza kutulutsa kowala kwambiri, nthawi yowola yayifupi, kukana kwa wailesi, kachulukidwe kakang'ono, nambala ya atomiki yapamwamba, kuzindikira kwakukulu motsutsana ndi ray ya gamma, yopanda hygroscopic ndi kukhazikika etc.

Chiyambi cha Zamalonda

LSO:Ce scintillator ndi galasi la LSO lopangidwa ndi ayoni a cerium (Ce).Kuphatikiza kwa cerium kumapangitsa kuti LSO ikhale yodziwika bwino, ndikupangitsa kuti ikhale chodziwikiratu cha radiation ya ionizing.LSO: Ce scintillators amagwiritsidwa ntchito kwambiri mu positron Emission Tomography (PET) scanner, chida chojambula chachipatala chomwe chimagwiritsidwa ntchito pozindikira ndi kuchiza matenda osiyanasiyana monga khansa, Alzheimer's ndi matenda ena amisempha.Mu PET scanners, LSO: Ce scintillators amagwiritsidwa ntchito kuti azindikire ma photon opangidwa ndi positron-emitting radiotracers (monga F-18) omwe amalowetsedwa mwa wodwalayo.Ma radiotracer awa amawonongeka ndi beta, kutulutsa mafotoni awiri mbali zosiyana.Mafotoni amaika mphamvu mkati mwa LSO:Ce crystal, kutulutsa kuwala kwa scintillation komwe kumajambulidwa ndikuzindikiridwa ndi chubu cha photomultiplier (PMT).PMT imawerenga chizindikiro cha scintillation ndikuchisintha kukhala deta ya digito, yomwe imakonzedwa kuti ipange chithunzi cha kugawa kwa radiotracer m'thupi.LSO: Ce scintillators amagwiritsidwanso ntchito pazinthu zina zomwe zimafuna zowunikira zowoneka bwino kwambiri, monga kujambula kwa X-ray, physics ya nyukiliya, fiziki yamphamvu kwambiri, ndi ma radiation dosimetry.

LSO, kapena lead scintillation oxide, ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pozindikira ma radiation ndi kugwiritsa ntchito kujambula.Ndi crystal scintillation yomwe imawala ikakumana ndi ma ionizing radiation monga gamma ray kapena X-ray.Kuwalako kumazindikiridwa ndikusinthidwa kukhala zizindikiro zamagetsi, zomwe zingagwiritsidwe ntchito kupanga zithunzi kapena kuzindikira kukhalapo kwa cheza.LSO ili ndi maubwino angapo kuposa zida zina zopangira scintillation, kuphatikiza kutulutsa kwapamwamba kwambiri, nthawi yowola mwachangu, kukonza bwino mphamvu, kutsika pang'ono, komanso kachulukidwe kwambiri.Zotsatira zake, makhiristo a LSO amagwiritsidwa ntchito kwambiri pazida zojambulira zamankhwala monga PET scanner, komanso pachitetezo ndi kuyang'anira chilengedwe.
