| Abstract: | The useful reconstruction technologies for neutron penumbral imaging are all linear method,and computed tomography(CT) is one of linear methods.The principle of the CT reconstruction for neutron penumbral imaging is introduced,and the detecting image with penumbral imaging,which is extracted and differentiated along radial direction,can be reconstructed by the CT method.The detecting imaging with different noises is decoded by convoluted backprojection method,and the advantages and disadvantages of the CT r... |
