Neutron radiography and computed tomography are effective tools for nondestructive investigation of internal structures of complex multi-material objects. Thermal neutrons are more effective at producing high-contrast radiographs of objects composed of elements with relatively low atomic numbers.
Neutron radiography and computed tomography may be used to investigate internal structures of complex multi-material objects nondestructively. Thermal neutrons are more effective at producing high-contrast radiographs of objects composed of elements with relatively low atomic numbers (Z). A capability to produce high-quality CT reconstructions from both thermal and fast neutron computed tomography (nCT) using a lens-coupled imaging was demonstrated using various Additively Manufactured (AM'd) and Electrical Discharge Machining (EDM) phantoms, with layers and distinct features, made with intentional voids and out of high- and low-Z elements.
