Transversal views of the HN patient images reconstructed by different methods. From left to right in the first row, the images are regular dose FDK reconstruction, reconstructions from the 3DDL, 2DDL and TF methods, respectively. From left to right in the second row, the images are reconstructed by the FDK, 881DL, 818DL and 188DL methods, respectively. The last two rows show the corresponding zoomed-in ROIs of the box in the first two rows. The display window is [−750 750] HU.
