Abstract

Radiographic inspection is an essential tool in the nondestructive evaluation of devices such as solid rocket motors which must work properly when fired. The advent of real-time radiographic (RTR) inspection systems has dramatically improved the throughput and coverage of these inspections over film-based techniques. The RTR inspection, however, is only as sensitive as the system used. Qualitative measures of image quality which were originally developed for film-based inspection have been applied to these real-time systems. While these qualitative measures are useful, there is a clear need to develop quantitative measures which are more appropriate for the RTR inspection systems which do not rely on a subjective judgement and which can be used to indicate the cause of problems in the system.
