Kingheng amapereka mitundu yosiyanasiyana kuti agwiritse ntchito.
Titha kupereka CsI(Tl), CsI(Na), CdWO4, LYSO,LSO, YSO, GAGG, BGO scintillation arrays.Kutengera kugwiritsa ntchito TiO2/BaSO4/ESR/E60 amagwiritsidwa ntchito kwambiri ngati zinthu zowunikira pakudzipatula kwa pixel.Kukonzekera kwathu kwamakina kumasunga kulolerana kwakung'ono kukhathamiritsa mawonekedwe amtundu wamagulu kuphatikiza kulolerana, kukula, kuyankhula kochepa komanso kufanana etc.
Mtundu: Linear array (1D) kapena Matrix array(2D)
Tikhoza kukupatsani:
● Mulingo wa pixel wocheperako ulipo
● Kuchepetsa kwapang'onopang'ono
● Kufanana kwabwino pakati pa mapixel mpaka mapixel/magulu osiyanasiyana
● TiO2/BaSO4/ESR/E60
● Kusiyana kwa Pixel: 0.08, 0.1, 0.2, 0.3mm
● Kuyezetsa ntchito kulipo
● Kusachepera kwa pixel ndi 0.2 * 0.2mm
● Kusintha mwamakonda kulipo malinga ndi parameter
Zithunzi za GAGG
GAGG (Gd3Al2Ga3O12) ndi mtundu wa zinthu za scintillator zomwe zadziwika kwambiri pozindikira ma radiation chifukwa cha kutulutsa kwake kwakukulu, nthawi yoyankha mwachangu, komanso kuwongolera mphamvu kwamphamvu.Ndikofunikira makamaka pakuwunika kwa gamma-ray, pomwe kuyeza kolondola kwamphamvu kwamphamvu kumafunikira.
Gulu la GAGG lili ndi ntchito zambiri m'malo monga nyukiliya physics, kujambula kwachipatala, ndi chitetezo cha kwawo.Mwachitsanzo, angagwiritsidwe ntchito mu positron emission tomography (PET) scanner, zomwe zimagwiritsidwa ntchito pojambula zachipatala kuti ziwone kugawidwa kwa radiotracers m'thupi.Ma GAGG array atha kugwiritsidwanso ntchito powunikira ma radiation portal kuti azindikire ndikuzindikira komwe kungayambike ma radiation pa eyapoti, madoko ndi malo ena oyendera.
LYSO gulu
Ma LYSO arrays atha kugwiritsidwa ntchito ngati mawonekedwe a GAGG, monga PET scanner ndi ma radiation portal monitors.Atha kugwiritsidwanso ntchito mumitundu ina yamakina ojambulira, monga makamera a gamma ndi SPECT (single photon emission computed tomography) zowunikira zamankhwala.
Ubwino waukulu wa LYSO pa GAGG ndi kuchuluka kwake komanso nambala ya atomiki, zomwe zimapangitsa kuti ikhale yogwira mtima pozindikira kuwala kwa gamma.Komabe, LYSO ndiyokwera mtengo kwambiri kuposa GAGG ndipo ili ndi zoletsa zina pakutentha kwake komanso kuuma kwa ma radiation.
Ponseponse, magulu onse a GAGG ndi LYSO ndi zida zofunika zowunikira komanso kujambula ma radiation pamagwiritsidwe osiyanasiyana, ndipo akupangidwa mosalekeza kuti azichita bwino komanso azisinthasintha.
