Film X-ray inspection has been a standard NDT process for the Aerospace Industry for decades. Weaknesses of film include the time and cost to process and the difficulty to store or transmit the final images. While Digital Radiography (DR) is less time-consuming and easier to distribute, the higher quality images traditionally provided by film far out-weighed the weaknesses.
Recent advances in Digital Radiography will not only meet film image quality, but can exceed these requirements. Key considerations such as Signal to Noise Ratio, Contrast Sensitivity and Spatial Resolution must be taken into account. ASTM E2597 establishes a quantitative method to qualify digital detectors.
This presentation will cover the latest DR technologies, the underlying technology, types of panels, integration speed, and appropriate applications. We will cover the new definitions for “bad pixels” that have recently been published, and explain how to compare between manufactures.
Summary: This presentation compares how Digital Radiography compares with film, and the impact that the ASTM standard E2597 has on inspection of Aerospace materials.
