Transmission reconstruction data in tomographic gamma scanning

The experiment used Eu152 to scan the sample. The sample voxel contains aluminum, wood, graphite and polyethylene. Because the density of other materials voxel is not consistent, transmission reconstruction only compares the error of the linear attenuation coefficient of reconstructed aluminum voxel. aluminium_mu.txt: Method to calculate standard linear attenuation coefficient of aluminium at 344.3 keV and 411.2 keV energy 344.3keV(SART).csv: Linear attenuation image of aluminum reconstructed by SART at 344.3 keV energy411.2keV(SART).csv: Linear attenuation image of aluminum reconstructed by SART at 411.2 keV energy411.2keV(PICCS-LR).csv: Linear attenuation image of aluminum reconstructed by PICCS-LR at 411.2 keV energy
