3D Reconstruction of the Rotational Axis in Fission Neutron Tomography

Abstract. In tomography, a misalignment of the rotational axis can introduce blurring. We present intensity-based image registration to calculate the axis’ components in three-dimensional space. We have shown that the axis can be deduced from rotating and translating image pairs acquired at 0° and 180°. No prior experimental calibration or any a-priori knowledge about the system’s mechanical setup is necessary. Three samples of different symmetry and homogeneity were examined to experimentally assess the numerical effects of image registration.
