摘要
研究了大型集装箱CT系统的图像重建技术,给出了卷积反投影算法的基本原理、实现过程,以及目前得到的重建图像。经实际检验,应用该算法重建的图像清晰,能够识别铸造工件中的孔及树木的年轮。
The image reconstruction algorithm of the container CT system are researched. The principle and the realized process of the filtered backprojection(FBP) algorithm are introduced. The clear reconstruction image shows that the algorithm is effectual. The hole in the work piece and the annual ring of the wood can be recognized from the image distinctly.
