Compact Support FDK Kernel Reconstruction Model Base on Approximate Inverse

الملخص EN

A novel CT reconstruction model is proposed, and the reconstruction is completed by this kernel-based method.

The reconstruction kernel can be obtained by combining the approximate inverse method with the FDK algorithm.

The computation of the kernel is moderate, and the reconstruction results can be improved by introducing the compact support version of the kernel.

The efficiency and the accuracy are shown in the numerical experiments.
