Computed Neutron Tomography from Real-Time Radiographic Images

A real-time neutron radiography facility was constructed including the capability of neutron tomography. A tomography algorithm, using the convolution method, was programmed on an Intellect 100 Image Processing System. The method produced results near the theoretical resolution limits for a given number of projections. A tomographic resolution of at least 1.3 mm was demonstrated using 200 projections. Computer running time for the convolution method was found to be about 30 seconds for each projection used.
