摘要

作者使用最近开发的PET扫描仪模型来模拟TTV03 CEA-LETL飞行时间(TOF) PET扫描仪的某些特性。发现一对探测器的TOF分辨率为400 ps (FWHM)，而TTV03 LETI扫描仪测量的TOF分辨率为750 ps。作者计算了真实、随机和噪声有效计数率作为较低能量阈值的函数，并与实验测量结果很好地吻合。

A simulation study of the LETI TTV03 TOF PET scanner

The authors use a recently developed PET scanner model to simulate certain characteristics of the TTV03 CEA-LETL time-of-flight (TOF) PET scanner. It is found that the TOF resolution for a pair of detectors is 400 ps (FWHM), as compared to 750 ps measured with the TTV03 LETI scanner. The authors calculate the true, random, and noise effective count rates as functions of the lower energy threshold and find good agreement with experimental measurements.<>
