Ce LYSO Scintillator Crystal

13 Aug 2019

Description

Ce:LYSO Scintillator Crystal—A non-hygroscopic high performance scintillator

Cerium doped LYSO crystals coupled to SiPMs have been widely incorporated into PET systems recently and promising results have been reported. Ce:LYSO is a inorganic scintillation crystal with good comprehensive performance, its luminous decay time is short, high light yield, the gamma ray with strong stopping power, at the same time, physical and chemical performance is stable, not deliquesce in the air, has been widely applied in nuclear medicine imaging, nuclear radiation measurement, safety inspection, etc. Ce:LYSO is a mixed LSO/YSO non-hygroscopic crystal that offers high density (7.1,10%Y), high light output (26000–30000 ph/MeV), good energy resolution( ~10%) and short decay time (40 ns). We are focusing on providing high performance scintillation crystals for our customers according to their requirements.

The continuing demand for better image quality, shorter scan time, and lower radiation dose to the patient has resulted in ongoing research in the field of positron emission tomography (PET) .The design of a PET scanner is specially challenging since it should not compromise high spatial resolution, high sensitivity, high count-rate capability, and good energy and time resolution. Scintillators with fast decay time characteristics have always been the radiation detection materials pursued by high-energy physics experiments, nuclear physics and positron emission tomography. They are beneficial for high count rate and time resolution of nanosecond and sub-nanosecond orders. Ce:LYSO have become the most commonly used scintillators in PET detector design studies since the early 2000s, as they offer a good trade off among the aforementioned factors.
