摘要

A superior method for nondestructive evaluation has been developed using a neutron/X-ray combined computed tomography system (NXCT) at the Missouri University of Science & Technology. The NXCT system at Missouri S&T is the first such imaging platform and synthesis method to be developed. The system is housed within the Missouri S&T Reactor building. The neutrons are obtained directly from the reactor core, and the X-rays are obtained from a nearby X-ray source. This novel imaging method holds great promise for nondestructive material detection and analysis. The characterization of the newly developed system is imperative to the evaluation of imaging system performance and associated parameters. The NXCT system will be evaluated in terms of image uniformity, linearity and spatial resolution characteristics. Additionally, the correlation of the applied beam intensity, resulting image quality, and system sensitivity will be investigated. In this presentation, an overview of the NXCT system design will be provided along with characterization methods and information on the analytical and experimental results. Furthermore, precision techniques to improve system performance as well as correcting imaging artifacts will be described.
