Industrial CT Data

In addition to X-Ray radiography, the use of 3D computed tomography in NDT has created powerful new possibilities, but also new challenges for the inspection and testing process. Industrial CT volumes are generally quite large, which leads to several hundred MB to one or more GB of raw data per scan, which need to be processed, visualized, and analyzed interactively in order to enable an efficient workflow for the expert user. Real-time volume rendering has become an essential tool for visualizing industrial volumes. However, for NDT practitioners visualization is just one part of the workflow, which includes a variety of processing tasks such as defect detection and quantification, computing statistical measures and properties such as material porosity, performing accurate measurements and comparisons, and many more. We work in cooperation with the Austrian Foundry Research Institute (ÖGI) with the goal to explore industrial CT volumes in order to facilitate the important processes of quantification and quality assessment in a fully interactive, visualization-driven manner. These approaches are not limited to cast metal parts, but are also applicable to other materials like concrete, wood, asphalt, plastics, ceramics, and composite materials.
