Compact Support FDK Kernel Reconstruction Model Base on Approximate Inverse
Figure 2
Original phantom and reconstruction results of the middle plane. (a) is the original phantom of the midplane. (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) (f), respectively.
