Selected electronic, digital x-ray imaging systems and techniques were evaluated as possible replacements for the use of x-ray film at Air Force field aircraft maintenance facilities. Incentives for the introduction of digital systems include the elimination of recurring costs of film, processing, and waste disposal, and the advantages of electronic data analysis, digital signal processing, and the ease of storage, retrieval, and transfer of digital data. Initial experimental evaluations included photostimulable storage phosphors, scintillator-camera systems, flat panel imagers and the reverse geometry method. The technical evaluations were conducted with a test object consisting of typical honeycomb structure containing various faults, line pair gages, and image quality indicators on ¼–inch aluminum. Several electronic systems were capable of meeting most of the technical requirements for x-ray inspection, with system prices attractive for field locations with annual film costs in the range of $15,000 or more. All the electronic methods eliminate processing chemicals and offer advantages in certain applications. However, the storage phosphor systems were particularly well suited for field implementation because of their similarity to film, but without most of the recurring costs and the environmental problems associated with the use of film. These evaluations were conducted under a Small Business Innovation Research (SBIR) Phase I program. More extensive system evaluations are planned as the program continues into an SBIR Phase II project.
