An improved method of analyzing radiographs has been developed to satisfy the requirement for 100 inspection of ballistic shells at the loading plant. The new automated technique incorporates rapid processing and the reduction of human interaction consequently, the possibility of human error is sharply reduced. The improved technique was developed for specific application to the Amatex alternate-fill program. Much of the manual manipulation of the radiographs and handling of data was automated using a Tektronix 4014-1 graphics terminal, an opaque Tektronix 4954 graphics tablet, and a telephone link to a CDC 6600 computer. If the technique were modified to incorporate a dedicated minicomputer and a transparent graphics tablet, it would be suitable for use in loading plants. No improvement has been made in the initial analysis of the radiograph. An experienced X-ray technician is still required to read the radiograph, mark the defect boundaries, and make annotations. However, research is also being conducted to automate this portion of the analysis.
