Figure 7: From left to right column, reconstructed slices of Shepp-Logan low contrast, ForBild head and Defrise disk phantom, respectively, at 𝑥 = 0 . From top row to bottom row, reconstruction with FDK algorithm, Hu’s algorithm, T-FDK algorithm, CFDKW-1, and CFDKW-2 respectively. Display windows are [ 0 . 9 8 1 . 0 5 ] , [ 1 . 0 1 1 . 0 9 ] and [ 0 . 5 0 . 7 ] for Shepp-Logan, ForBild head and Defrise disk phantom, respectively.
