Illuminated Essence - Cutting-Edge LSO (Ce) Crystal rau Kev Txhim Kho Spectral Sensitivity
Taw qhia ntawm lub thawv wafer
Peb lub LSO (Ce) siv lead ua sawv cev rau qhov siab tshaj plaws ntawm cov khoom siv scintillation, muab kev ua tau zoo tshwj xeeb hauv ntau yam kev siv. Tsim nrog kev ua kom raug thiab kev txawj ntse, lub siv lead ua no yog doped nrog cerium (Ce) los txhim kho nws cov teeb pom kev zoo thiab kev teb spectral.
Lub LSO (Ce) siv lead ua muaj lub zog daws teeb meem zoo tshaj plaws thiab lub sijhawm ua haujlwm, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau positron emission tomography (PET), gamma-ray spectroscopy, thiab lwm yam kev siv duab kho mob thiab kev kuaj pom hluav taws xob. Nws lub teeb pom kev zoo thiab lub sijhawm lwj sai ua kom muaj kev kuaj pom tseeb thiab txhim khu kev qha ntawm gamma rays thiab lwm yam hluav taws xob ionizing.
Nrog nws cov kev ua tau zoo thiab kev ntseeg siab, peb lub LSO (Ce) siv lead ua teeb tsa tus qauv tshiab rau cov ntaub ntawv scintillation, ua rau muaj kev nce qib hauv kev tshawb fawb, kev kuaj mob, thiab kev ruaj ntseg hauv tebchaws. Paub txog kev rhiab heev thiab kev raug nrog peb lub LSO (Ce) siv lead ua, tsav tsheb tsim kho tshiab thiab kev tshawb pom hauv ntau qhov chaw.
