Polychromatic Iterative Statistical Material Image Reconstruction for Photon-Counting Computed Tomography
Table 1
Results of the accuracy analysis of the algorithm with and w/o regularization (regul.). The material fractions were measured after 1000 iterations in the respective material images within ROIs located as indicated in Figures 4(a) and 4(b). The standard deviation of the ROI data measures the fluctuation induced by the forward- and back-projector. The values of quantify the offset between the ground truth and the material fraction after 1000 iterations.
