Compact Support FDK Kernel Reconstruction Model Base on Approximate Inverse
Figure 5
Original Turbell clock and reconstruction results. (a) is the original Turbell clock. (b) is the reconstruction result with the Radon kernel. (c) is the result with the original FDK kernel model. Results with the compact FDK kernel model where the radius , 40, and 4 are shown in (d), (e) and (f), respectively.
