On-Line X-Ray Inspection of Materials and Structural Components Using Discrete Element X-Ray Detectors for Digital Radiographic and Computed Tomographic Evaluation

Abstract

This project was designed to study the effectiveness of industrial computed tomography (CT) and digital radiography (DR) as inspection techniques for the evaluation of materials and structural components manufactured on-line. The results indicate that computed tomography is an appropriate technique if speed and cost are not critical considerations. Digital radiography is the faster technique, but provides less information about the material. Limited view tomography (LVT), which is a simplified form of computed tomography, was compared and found to provide a good compromise between computed tomography and digital radiography when a priori knowledge of material structure is available. For some material configurations, it provides virtually complete computed tomography data in a fraction of the time required for full view computed tomography data collection and reconstruction. It offers the greatest potential for the productive cross-sectional characterization of composite materials. (jg)
