Single Photon Emission Computed Tomography Spect High Thermal Conductivity Gagg Crystal

Single Photon Emission Computed Tomography (SPECT) GAGG(ce) scintillator

Ce: GAGG crystal exhibits stable physical and chemical properties, high thermal conductivity, and resistance to harsh environments. It exhibits excellent scintillating performance, for example, high scintillating efficiency, high light yield, and fast decay time. Ce: GAGG crystals are widely used in photomultiplier tubes, photoelectric counters, scintillation screens, and other devices. And used in high-energy particle detection and other fields, such as beta rays, gamma rays. Because of the excellent scintillation performance of Ce: YAG crystal, it is widely used in CT, scanning electron microscope SEM and other equipment. In particular, the linear response of GAGG crystals to gamma rays indicates that Ce: GAGG crystals are a promising medical imaging technology, such as X-ray photography, X-ray computed tomography (CT), and positron emission tomography (PET). ). Single crystal scintillators are often used in scanning electron microscopy (SEM).
