Development of next generation PET system

我们已经证明使用LFS振荡器和MPPC光传感器可以得到合适的结果。这些结果有望在下一代PST系统中得到。LFS将伽马射线转化为电子的效率高，闪烁的光产率高，脉冲时间短，达到了良好的时间分辨率。MPPC传感器还具有良好的时间分辨率，可以产生短而快速的输出信号。因此，以上两者的结合将成为下一代PET系统的良好单元。

We have shown suitable results would be given by using LFS scitnillators and MPPC photo-sensors. Those results are expected to have with the next generation PST system.LFS has a high efficiency to convert the gamma rays to the electrons and high light yield of scintillation which has short time pulse to achieve good time resolution. The MPPC sensor has also good time resolution to generate short and rapid output signals. Therefore a combination of above two will make a good unit for the next generation PET system.
