摘要：

Fast neutron computed tomography (nCT) allows for structural examination of dense objects composed of both low- and high-atomic number elements. nCT data was collected at the Ohio State University Research Reactor’s fast neutron beam facility. Two imaging phantoms of various sizes and shapes, made of stainless steel, lead, and antimony, and containing High-Density Polyethylene (HDPE) inserts, were employed for demonstration. A total of 360 projections per each configuration of phantoms and respective inserts were collected in as low as 3 h. The voxel volume is determined to be ~ 104 cubic micron. 3D reconstructions clearly revealed the internal structure of the phantoms and features in HDPE inserts shielded by high-Z materials.
