Khoom Taw Qhia
LYSO, los yog lutetium yttrium oxide orthosilicate, yog ib qho siv lead ua siv lead ua feem ntau siv hauv cov khoom siv kho mob xws li PET (Positron Emission Tomography) scanners.LYSO crystals paub txog lawv cov txiaj ntsig siab photon, lub sijhawm tawg sai, thiab kev daws teeb meem zoo heev, ua rau lawv zoo tagnrho rau kev kuaj pom gamma rays tawm los ntawm radioisotopes hauv vivo.LYSO crystals kuj muaj qhov qis qis tom qab, txhais tau tias lawv sai sai rov qab mus rau lawv lub xeev qub tom qab raug hluav taws xob, tso cai rau cov duab kom tau txais thiab ua tiav sai dua.
Qhov zoo
1. High light output: LYSO crystals muaj photon yield siab, uas txhais tau hais tias lawv tuaj yeem ntes tau ntau ntawm gamma rays thiab hloov mus rau hauv lub teeb.Qhov no ua rau cov duab ntse dua, muaj tseeb dua.
2. Lub sij hawm lwj sai: LYSO siv lead ua muaj lub sij hawm tawg sai, uas yog, nws tuaj yeem rov qab mus rau qhov qub qub tom qab raug gamma tawg.Qhov no tso cai rau kom tau txais cov duab nrawm dua thiab ua tiav.
3. Kev daws teeb meem zoo heev: LYSO crystals tuaj yeem paub qhov txawv ntawm gamma rays ntawm lub zog sib txawv dua li lwm cov ntaub ntawv scintillation.Qhov no tso cai rau kev txheeb xyuas zoo dua thiab ntsuas ntawm cov isotopes radioactive hauv lub cev.
4. Tsawg afterglow: Lub afterglow ntawm LYSO siv lead ua yog qhov tsawg, uas yog, nws muaj peev xwm sai sai rov qab mus rau nws qub zoo tom qab irradiated.Qhov no txo cov sij hawm xav tau los tshem cov crystals ua ntej noj cov duab tom ntej.5. Kev ntom ntom ntom: NYSO Crystal muaj siab ntom ntom ntom, uas yog haum rau me thiab cog cov cuab yeej kev kho mob xws li cov tsiaj kuaj.
