Correction of scattering neutron effects on neutron CT

Correction of the scattering neutron effects in neutron computed tomography (CT) has been carried out. By subtracting the component of scattering neutrons in CT projection data, only the corrected direct transmitting component through objects is treated. By using the correction of the scattering component on neutron CT, the relatively low contrast on them by neutron electronic imaging method (TV) has been improved. Quantitative analyses with neutron CT have shown a better linear relationship between the neutron macroscopic cross sections and the CT outputs of metal objects.
