Compact Support FDK Kernel Reconstruction Model Base on Approximate Inverse

Figure 4

Original phantom and reconstruction results of the plane parallel and 20 mm apart from the midplane. (a) is the original phantom of the plane. (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.
