摘要
在类似大型集装箱检测系统的实验平台上完成了一系列有关材料识别的实验。实验结果表明,在5-10MeV的能量范围内,大型集装箱检测系统利用双能X射线技术根据有效原子序数识别材料组是可行的。
SART is an important arithmetic of image reconstruction,in which the projection computation takes over half of the reconstruction time. An efficient way to compute projection coefficient matrix together with memory optimization is presented in this paper. Different from normal method, projection lines are located based on every pixel, and the following projection coefficient computation can make use of the results. Correlation of projection lines and pixels can be used to optimize the computation.
