An Experiment Simulating the Scattering Factors of Cross-Talk Noise
摘 要
模拟了工业CT中射线束穿过物体后的散射情况。采用较强的60Co源和体积小而探测效率高的CdZnTe探测器,经长时间测量和利用matlab处理数据后,射线穿过物体后在出射方向的0°~2°间有较高的能量沉积,然后随着角度的增加能量沉积迅速下降。因此,在设计和选用探测器阵列时应考虑0°~2°之间的散射效应。
Abstract
This text simulates the scattering rays from the industry CT get through the material through an experiment. This experiment used a high intension source 60Co and a small bulk but high efficiency CdZnTe detector, through 24 hours measuring and matlab calculating, the results showed that rays had a high energy aggradations between 0-2 degrees from the collimation direction after the rays was collimated, then the energy aggradations decreased quickly as the angle increasesd, it shows that one should think about the aggradations affection between 0-2 degrees when design and select the detector rays.
