ʻO ka hui ʻana o ka Scintillation, ʻo ka ʻĀpana Scintillator, ka Matrix

Hōʻuluʻulu Manaʻo, Lahui Scintillator, Kiʻi Hōʻike ʻia ʻo Matrix

wehewehe pōkole:

ʻO kā mākou pono:

● Loaʻa ka nui pixel liʻiliʻi

● Hoʻemi ʻia ke kamaʻilio optical

● Hoʻohui maikaʻi ma waena o ka pixel a me ka pixel/ array to array

● TiO2/BaSO4/ESR/E60

● Pixel Gap: 0.08, 0.1, 0.2, 0.3mm

● Loaʻa nā hoʻokolohua hana

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

Hāʻawi ʻo Kinheng i nā ʻāpana like ʻole no ka hoʻopau ʻana i ka noi

Hiki iā mākou ke hāʻawi iā CsI (Tl), CsI (Na), CdWO4, LYSO, LSO, YSO, GAGG, BGO scintillation arrays.Ma muli o ka noi ʻo TiO2/BaSO4/ESR/E60 i hoʻohana nui ʻia e like me ka mea noʻonoʻo no ka hoʻokaʻawale pixel.Mālama kā mākou hana ʻenehana i ka liʻiliʻi liʻiliʻi e hoʻomaikaʻi i nā waiwai kino o ka array e like me ka hoʻomanawanui, ka nui, ke kamaʻilio liʻiliʻi liʻiliʻi a me ka like ʻole.

Hana Mechanical No ka Hui

Ma muli o ka hoʻohana hope ʻana o ka hui pū ʻana, nui nā ʻano hoʻolālā mechanic mai Kinheng e hālāwai me ka ʻoihana nānā olakino a palekana.

Hoʻohana nui ʻia ka laina laina 1D no ka ʻoihana nānā palekana, e like me ka bagger scanner, aviation scanner, 3D scanner a me NDT.Mea me CsI(Tl), GOS:Tb/Pr Film.

GAGG:Ce, CdWO4 scintillator etc.. Hoʻohui pinepine ʻia lākou me ka laina laina Silicon Photodiode no ka heluhelu ʻana.

Hoʻohana maʻamau ʻia nā ʻano 2D no ke kiʻi kiʻi, me ka lāʻau lapaʻau (SPECT, PET, PET-CT, ToF-PET), SEM, kāmele gamma.Hoʻohui pinepine ʻia kēia mau ʻano 2D me ka array SiPM, ka laʻana PMT no ka heluhelu ʻana.Hāʻawi ʻo Kinheng i nā ʻāpana 2D me LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator etc.

Aia ma lalo iho nā kiʻi hoʻolālā maʻamau a kinheng no 1D a me 2D array no ka ʻoihana.
