Matou Fa'amanuiaga:

● La'ititi la'ititi pika o lo'o avanoa

● Faʻaitiitia le faʻaogaina o fesoʻotaʻiga

● Lelei tutusa i le va o pixel i pixel/ array i array

● TiO2/BaSO4/ESR/E60

● Pixel Gap: 0.08, 0.1, 0.2, 0.3mm

● avanoa su'ega fa'atinoga

Kinheng e ofoina atu faʻasologa eseese mo le faʻauʻuga talosaga

E mafai ona matou saunia CsI(Tl), CsI(Na), CdWO4, LYSO,LSO, YSO, GAGG, BGO scintillation arrays.Faʻavae i luga o le talosaga TiO2 / BaSO4 / ESR / E60 o loʻo faʻaaogaina faʻapitoa e avea ma mea e faʻaalia mo le vavaeeseina o pika.O a matou faʻagasologa faʻainisinia e faʻatumauina le laʻititi laʻititi e faʻamalieina ai mea faʻaletino a le array e aofia ai le faʻapalepale, fua, tautalaga laʻititi-koluse ma tutusa ma isi.

Fuafuaga Faʻainisinia Mo le Faʻapipiʻiina

Faʻavae i luga o le faʻaogaina o le faʻaogaina o le faʻapipiʻiina, e tele ituaiga masini masini mai Kinheng e faʻafeiloaʻi ai le falemaʻi ma le saogalemu o asiasiga.

1D Linear array e masani ona faʻaaogaina mo suʻesuʻega saogalemu, e pei o le taga siaki, vaalele vaalele, 3D scanner ma le NDT.Mea e aofia ai CsI(Tl), GOS:Tb/Pr Ata Ata.

GAGG:Ce, CdWO4 scintillator ma isi.

2D array e masani ona faʻaaogaina mo ata, e aofia ai fomaʻi (SPECT, PET, PET-CT, ToF-PET), SEM, gamma kamera.O nei laina 2D e masani ona faʻapipiʻiina ma le SiPM array, PMT array mo le faitau.Kinheng saunia 2D array e aofia ai LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator ma isi.

O lo'o i lalo ata o ata masani a kinheng mo le 1D ma le 2D array mo alamanuia.
