(color online) FDK reconstructions with real CT projections. (a), (c), (e) FDK reconstructions with full views (i.e., 360 projections) and (b), (d), (f) FDK reconstructions with sparse views (60 projections). From the top to the bottom row, images are at the 72th, 192th (central transverse section), and 302th transverse sections. The displayed gray scale window is [0.01 0.06].
