Sridhar Tripathy, Jaydeep Datta, Nayana Majumdar, Supratik Mukhopadhyay

摘要:

这项工作报告的数值模拟和统计测试进行研究的原型成像装置的性能开发的材料歧视使用μ子散射层析成像(MST)。用模式识别方法(PRM)对重建图像进行处理,以区分低Z和高Z材料。同样的方法已被应用到检查的性能的设置在识别的测试对象的形状。设计参数的设置,如μ子探测器的面积,它们的物理位置,以及它们的空间分辨率等进行了讨论。为了评估新提出的PRM的功效,将结果与基于聚类发现的另一种技术进行了比较。

英文摘要:

This work reports numerical simulations and statistical tests carried out to study the performance of a prototype imaging setup to be developed for material discrimination using Muon Scattering Tomography (MST). The reconstructed images have been processed with a Pattern Recognition Method (PRM) to discriminate the low-Z and high-Z materials. The same method has been applied to examine the performance of the setup in recognizing the shape of the test objects. Design parameters of the setup, such as area of the muon detectors, their physical placement, along with their spatial resolution, etc. have been discussed. To evaluate the efficacy of the newly proposed PRM, the results have been compared to another technique based on cluster finding.
