Medical imaging Industrial CT scanner GOS Matrix GOS scintillator Array
Gadolinium oxysulfide or GOS (Gd2O2S:Pr) is a kind of ceramic with hexagonal system structure, it has a good chemical stability and machinability and is harmless to environment. GOS doped with rare earth ion has relatively high light output and extremely low afterglow, which is less than 0.1% at 3 ms. GOS scintilaltor ceramic has an emission peak spectral range at 470 ~ 900 nm, which is well matched with the spectral sensitivity of silicon photodiodes (Si PD).

Mechanical design for assembling:
Based on the end use of assembled array, there are many kinds of mechanic design from Kinheng to meet the medical and security inspection industry.
1D Liner array are mainly used for Security inspection industy, such as Bagger scanner, Aviation scanner, 3D scanner and NDT. Material Including CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. They are typically coupled with Silicon Photodiode linear array for read out.
2D array are normally used for imaging, including Medical(SPECT, PET, PET-CT, ToF-PET), SEM, Gamma camera. These 2D array are typically coupled with SIPM array, PMT array for read out. Kinheng provide 2D array including LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator etc.
Below is kinheng’s typically design drawing for 1D And 2D array for industry.
