Positron emission tomography (PET) plays an important role in disease prevention and detection. In order to improve the performance of PET system, this paper reviewed the development of some scintillation crystals for PET based on the luminescence mechanism and scintillation performance. At present, cerium-doped lanthanum bromide has a superior performance in PET scintillation crystal, but it cannot replace yttrium lutetium silicate as a mainstream crystal in PET system due to the difficulty of moisture absorption and processing. Cerium-doped gadolinium gallium aluminum garnet crystal is expected to become one of the alternative materials for PET scintillation crystal due to its good time resolution and spatial resolution. The future research direction of scintillation crystals in PET field is to explore some novel crystals suitable for time-of-flight detection and depth of interaction detection technology.

正电子发射断层成像(PET)在疾病预防检测等方面具有重要价值,为提升PET系统性能,本工作从闪烁晶体的发光机理和闪烁性能出发,综述了部分PET用闪烁晶体的发展状况。目前PET用闪烁晶体中,掺铈溴化镧性能优异,但由于吸湿和加工难而未能取代硅酸钇镥成为PET系统中的主流晶体;掺铈的钆镓铝石榴石晶体由于良好的时间空间分辨率,有望成为PET用闪烁晶体的替代材料之一。未来PET领域闪烁晶体的进一步研究方向是探寻适合基于飞行时间探测和基于作用深度探测技术的新型晶体等。

正电子发射断层成像(PET)在疾病预防检测等方面具有重要价值,为提升PET系统性能,本工作从闪烁晶体的发光机理和闪烁性能出发,综述了部分PET用闪烁晶体的发展状况。目前PET用闪烁晶体中,掺铈溴化镧性能优异,但由于吸湿和加工难而未能取代硅酸钇镥成为PET系统中的主流晶体;掺铈的钆镓铝石榴石晶体由于良好的时间空间分辨率,有望成为PET用闪烁晶体的替代材料之一。未来PET领域闪烁晶体的进一步研究方向是探寻适合基于飞行时间探测和基于作用深度探测技术的新型晶体等。

Positron emission tomography (PET) plays an important role in disease prevention and detection. In order to improve the performance of PET system, this paper reviewed the development of some scintillation crystals for PET based on the luminescence mechanism and scintillation performance. At present, cerium-doped lanthanum bromide has a superior performance in PET scintillation crystal, but it cannot replace yttrium lutetium silicate as a mainstream crystal in PET system due to the difficulty of moisture absorption and processing. Cerium-doped gadolinium gallium aluminum garnet crystal is expected to become one of the alternative materials for PET scintillation crystal due to its good time resolution and spatial resolution. The future research direction of scintillation crystals in PET field is to explore some novel crystals suitable for time-of-flight detection and depth of interaction detection technology.
