一种热中子CT图像预处理与后处理的集成方法

热中子CT成像是一种极为重要的核成像技术,借以进行被检物的无损检测与无损评价。针对热中子CT成像过程中产生一系列导致CT图像降质的因素,本文在探讨了影响中子CT成像图像降质的一些因素基础上,提出了将成像过程中的图像预处理与后处理技术进行统一考察和集成处理的方案。研究结果表明,基于MATLABGUI集成处理器,研究开发了一套集图像预处理与后处理技术于一体的处理程序分析方法,能够有效改善热中子CT成像的图像质量,为无损检测与评价提供可靠的保证,对热中子CT成像技术研究具有参考价值。

An Integrated Algorithm of Image Pre-processing and Post-processing in Thermal Neutron Computed Tomography (n-CT)

As a kind of extremely important nuclear imaging technologies,thermal neutron CT imaging technology can carry out Non-destructive testing and Non-destructive evaluating of detected samples.Based on a series of factors that lead to image degradation in the thermal neutron CT imaging process and the discussion of that,we present an integrated processing solution and developed a set of analytical software which investigating the image Pre-processing and post-processing technology based on MATLAB GUI integrated processor.The results of the research show that,the solution can effectively improve the thermal neutron CT images quality.These not only provide reliable guarantee for Non-destructive testing and evaluating,but also provide some reference value for thermal neutron CT imaging technology.
