Laser Part GAGG Doped Ce Scintillation Detector For Medical Imaging
GAGG(Ce) (Ce:GAGG, Gd3Al2Ga3O12) is new scintillator for single photon emission computed tomography(SPECT), gamma-ray and compton electron detection. Cerium doped GAGG have many properties that make it suitable for gamma spectroscopy and medical imaging applications. A high photon yield and emission peak around 520 nm makes the material well suited to be readout by Silicon Photo-multiplier detectors.
Ce: GAGG crystal (chemical formula Ce: Gd3Al2Ga3O12, also known as cerium-doped gadolinium aluminum gallium garnet crystal) is a scintillation crystal with excellent comprehensive performance, which is widely used in scientific research and industrial high-energy ray detection. Ce: The effective atomic number of the GAGG crystal is as high as 54.4, and the peak wavelength of the emission spectrum located at 520nm, which matches well with the sensitive wavelength range of the photomultiplier tube (PMT) and silicon photodiode (PD).
Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.
