Digital Radiography (DR)
Digital radiography is a fast and non-destructive technique frequently used for material inspection in the aerospace, automotive, and industrial manufacturing sectors. It is a fast and reliable tool to assess weakness, detect faults and characterize materials for raw material testing, product development, and quality control.
Direct Radiography uses X-ray-sensitive reusable plates that capture and convert the X-rays to light. Thin-film transistors translate the radiographic images to digital data in real-time and are seamlessly displayed on the computer. DR is much faster and produces higher quality images than traditional film imaging.
Computed Radiography was the first commercially available radiographic imaging technology with a separate image readout process. It replaces film in the conventional radiography imaging with phosphor imaging plate (IP). The imaging plates capture the image, that are scanned separately to produce a digital image. While not a rapid technique like DR, it is still much faster and environmentally friendly than conventional film radiography imaging and is a readily available radiography option.
Computed Tomography is a radiography imaging technique where thousands of 2D radiographic scans are stacked together to create 3D images through image processing. It is used for comprehensive material characterization.

Root cause analysis of any failed product, component, or material is the investigative study of why or how it failed, resolve the problem, and prevent the recurrence of failure.
Chemical analysis is routinely performed to identify unknown components, obtain physical characteristics or chemical composition, and determine the quality of materials.
