Data for: An Analytical Simulation Method for X-ray Fluorescence Computed Tomography

Figures presented in this folder present the comparison between data simulated by PENELOPE and XFCTLab, which have been used to confirm the correctness of analytical simulator proposed for X-ray fluorescence computed tomography. In the legend box of each plot, the number followed "PENELOPE" (e.g. PENELOPE 2e2) indicates how many photons have been simulated at each translation position. Due to the usage of variance reduction technique, it is assumed simulating 2 million photons per translation position with PENELOPE (indicated in figure as: PENELOPE 2e6) is sufficiently close to the ground truth.本文件夹内的图表展示了PENELOPE与XFCTLab两款仿真软件生成的仿真数据对比，该对比被用于验证所提出的X射线荧光计算机断层扫描（X-ray fluorescence computed tomography）解析型仿真器的正确性。每张图表的图例中，紧随“PENELOPE”字样后的数字（例如PENELOPE 2e2）代表该平移位置处模拟的光子总数。由于采用了方差缩减技术，本研究默认使用PENELOPE在每个平移位置模拟200万光子（图表中标记为PENELOPE 2e6）的仿真结果已足够接近基准真值。
