为了研究PET用LSO晶体中的光输运，我们使用Detect2000模拟了单晶和块探测器。我们设计了基本的实验来评估模拟的基本物理参数，并用一组单晶实验对模拟进行了基准测试。所研究的块检测器由硅酸氧镥晶体、光导和光电倍增管组成。模拟的结果进行了比较，实验检测器块的位置分布。通过改进我们的模拟来模拟实际检测器，创建了一个可用于优化检测器块性能的工具。
In order to study light transport in LSO crystals for PET, we simulated single crystals and block detectors using Detect2000. We devised basic experiments to evaluate fundamental physics parameters of the simulation and benchmarked the simulation with a set of experiments on single crystals. The block detectors that were studied were composed of Lutetium Oxyortho-Silicate crystals, a light guide and Photo Multiplier Tubes. The results of the simulation were compared to an experimental detector block's position profile. By refining our simulation to model actual detectors, a tool was created that can be used to optimize the performance of detector blocks.
