Study for a novel tomography technique using an imaging plate

A sinogram is directly recorded onto an imaging plate for neutron tomography, which has excellent capability to detect neutrons. A sinogram-recording-system and outline of the data processing are explained briefly. A tomogram of a test object is reconstructed and shown as the preliminary result. The linearity of CT values was experimentally confirmed up to 1.6 cm−1 of effective total macroscopic cross section, but about 10% lower CT value was observed at 2.7 cm−1. The linearity limitation and statistical character of CT values are discussed with regard to the dynamic range of the system as well as the effect of background components.
