GAGG:Ce (Gd3Al2Ga3O12) gadolinium aluminium gallium garnet e entsoeng ka cerium.Ke scintillator e ncha bakeng sa single photon emission computed tomography (SPECT), gamma-ray le Compton electron discovery.Cerium doped GAGG:Ce e na le thepa e mengata e etsang hore e tšoanelehe bakeng sa li-spectroscopy tsa gamma le lits'ebetso tsa litšoantšo tsa bongaka.Kotulo e phahameng ea photon le tlhoro ea tlhahiso e ka bang 530 nm e etsa hore thepa e lokele ho baloa ke li-detectors tsa Silicon Photo-multiplier.Epic crystal e hlahisitse mefuta e 3 ea GAGG: kristale ea Ce, e nang le nako ea ho bola kapele (GAGG-FD) kristale, e tloaelehileng (GAGG-Balance) kristale, khanya e phahameng (GAGG-HL) kristale, bakeng sa moreki libakeng tse fapaneng.GAGG: Ce ke scintillator e tšepisang haholo lefapheng la indasteri ea matla a phahameng, ha e ne e tšoauoa tekong ea bophelo tlas'a 115kv, 3mA le mohloli oa mahlaseli o sebakeng sa 150 mm ho tloha kristale, ka mor'a lihora tse 20 ts'ebetso e batla e tšoana le e ncha. ngoe.Ho bolela hore e na le tebello e ntle ea ho mamella lethal dose le phahameng tlas'a mahlaseli a X-ray, ehlile ho ipapisitse le maemo a mahlaseli le haeba ho ka tsoela pele ka GAGG bakeng sa NDT tlhahlobo e 'ngoe e nepahetseng e lokela ho etsoa.Ka thoko ho GAGG e le 'ngoe: kristale ea Ce, re khona ho e etsa hore e be mehala le 2 dimensional, boholo ba pixel le karohano li ka fihlelleha ho latela tlhoko.Re boetse re ntlafalitse theknoloji ea ceramic GAGG: Ce, e na le nako e betere ea ho rarolla ka tšohanyetso(CRT), nako ea ho bola ka potlako le tlhahiso e phahameng ea leseli.
