The sensitivity to feature and anomaly detection in industrial X-ray computed tomography CT systems is a function of CT system operating parameters. Established as a part of the envelope that strikes a balance between sensitivity, inspection time and cost. These parameter choices eventually find their way into CT system attributes configurations, components and procedures. CT system users are concerned with sensitivity requirements for specific instruction purposes, while CT system manufacturers are concerned with their implications for the systems physical constituents, assembly and control. This report discusses the attributes and the conversion to system constituents that must occur for a useful CT system specification to be prepared. The effect of attribute specification on CT system constituent costs are addressed. Understanding these issues is critical to the successful acquisition and implementation of a new CT system. Guidelines for the preparation and evaluation of CT specifications are provided.
