High-Energy Neutron Computed Tomography

High-energy neutron computed tomography can be used in instances where x-rays are unable to penetrate high Z materials. This allows imaging of low Z materials shielded by higher Z materials. Utilizing high energy neutrons from a “white” neutron source, a collaborative team at LANSCE has shown that this technique creates more detailed images used through a high Z material than can be obtained with x-ray imaging.
