Computer Simulation of Digital Projections-of-cuboid Object in CL System

    摘要
  • 摘要: X射线投影计算机仿真可以排除实际X射线断层扫描过程中的随机因素,更好地验证扫描方式、图像重建方法等的正确性,为实际系统的实现、完善以及重建算法的改进等提供理论依据。本文基于一种典型的计算机分层成像(CL)系统,针对电子线路板大多为长方体薄板的事实,研究了长方体构件的投影仿真计算方法;设计了仿真芯片模体,对其进行投影计算机仿真;并与系统实验结果对比,得到了较为满意的结果。该方法为后续改进图像重建算法、分析误差来源、校正伪影等研究提供了良好的基础。

     

    Abstract: Computer Simulation of X-ray Projections can be used to exclude the random errors during the X-ray tomography scan.It can be used for verifying the correctness of the scan mode and image reconstruction method,and providing theoretical basis for the actual system implementation and improvement and reconstruction algorithm.While most of the simulation focused on cylinder and ellipsoid,we make simulation of cuboid samples in typical CL system in this paper,as printed circuit is approximate sheet-like cuboid.We compared the Experimental and simulation results and get satisfactory results.The work provides a good foundation for improving image reconstruction algorithm,analyze errors and correct artifacts.
