In order to improve the quality of positron tomographic imaging, a time-of-flight technique combined with a classical reconstruction method has been investigated. The decay time of NaI(Tl) and bismuth germanate (BGO) scintillators is too long for this application, and efficiency of the plastic scintillators is too low. Cesium fluoride appears to be a very promising detector material. This paper presents preliminary results obtained with a time-of-flight technique using CsF scintillators. The expected advantages were realized.
为了提高正电子断层成像的质量，人们研究了一种将飞行时间技术与传统重建方法相结合的技术。碘化钠（铊）（NaI(Tl)）闪烁体和锗酸铋（BGO）闪烁体的衰变时间对于该应用来说太长，而塑料闪烁体的效率又太低。氟化铯似乎是一种非常有前景的探测器材料。本文展示了使用CsF闪烁体的飞行时间技术所获得的初步结果。预期的优势得以实现。
