| Abstract: | When using filtered backprojection algorithm in the reconstruction, the choice of CT's Kernel is very important toimaging quality. We have made an analysis on the kernels of ANATOM-2000 CT. Two of them are taken out for being compared with the Lewitt Kernel and they are very approximate to the Lewitt Kernel. |
| Keywords: | CT reconstruction backprojection filter kernel |
