● Boholo ba pixel bo teng
● Optical crosstalk e fokotsehile
● Ho lumellana ho hotle pakeng tsa pixel ho ea ho pixel / mefuta e mengata
● TiO2/BaSO4/ESR/E60
● Lekhalo la Pixel: 0.08, 0.1, 0.2, 0.3mm
● Teko ea tšebetso e teng
● Boholo bo tlase ba pixel ke 0.2*0.2mm

Lihlopha tsa GGG
GAGG (Gd3Al2Ga3O12) ke mofuta oa thepa ea scintillator e seng e tumme haholo lits'ebetsong tsa ho lemoha mahlaseli ka lebaka la tlhahiso ea eona e phahameng ea khanya, nako ea ho arabela ka potlako, le tharollo e babatsehang ea matla.E bohlokoa haholo bakeng sa spectroscopy ea gamma-ray, moo ho hlokahalang tekanyo e nepahetseng ea matla a mahlaseli a gamma.
Lihlopha tsa GAGG li na le lits'ebetso tse ngata libakeng tse kang fisiks ea nyutlelie, litšoantšo tsa bongaka, le ts'ireletso ea naha.Ka mohlala, li ka sebelisoa mecheng ea positron emission tomography (PET) scanner, e sebelisoang litšoantšong tsa bongaka ho bona ka mahlo a kelello ho ajoa ha radiotracers 'meleng.Li-array tsa GAGG li ka boela tsa sebelisoa ho li-portal monitor tsa mahlaseli ho bona le ho tseba mehloli e ka bang teng ea mahlaseli boema-fofane, boema-kepeng le libakeng tse ling tsa lipalangoang.
Sehlopha sa LYSO
Li-arrays tsa LYSO li ka sebelisoa lits'ebetsong tse ts'oanang le li-GAGG arrays, joalo ka li-scanner tsa PET le li-portal monitor tsa radiation.Li ka boela tsa sebelisoa mefuteng e meng ea mekhoa ea litšoantšo, tse kang lik'hamera tsa gamma le SPECT (single photon emission computed tomography) bakeng sa litšoantšo tsa bongaka.
Monyetla o ka sehloohong oa LYSO ho feta GAGG ke bongata ba eona bo phahameng le nomoro ea athomo, e etsang hore e sebetse hantle ho lemoha mahlaseli a gamma.Leha ho le joalo, LYSO e boetse e theko e boima ho feta GAGG 'me e na le meeli e itseng ho latela mocheso oa eona le boima ba mahlaseli a kotsi.
Ka kakaretso, lihlopha tsa GAGG le LYSO ke lisebelisoa tsa bohlokoa bakeng sa ho lemoha mahlaseli a kotsi le ho nahana ka mekhoa e fapaneng ea ts'ebeliso, 'me li ntse li tsoela pele ho ntlafatsoa bakeng sa ts'ebetso e ntle le ho feta.
