CT X-ray imaging

The capabilities of CT X-ray imaging techniques are evolving and usefulness  to industrial applications are rapidly increasing. CT X-ray imaging uses a sequence of X-ray images to create a computed 3D image stack of a given sample. The data generated contains information about the materials involved and their geometrical features, such as voids and defects. This can be used for non-destructive analysis, or the information can provide insight to identify locations for further analysis. For metrological analysis, the data can be compared to a CAD model or simulation results for comparison. As an example, complex cavities in tools for molding can be compared to the the original CAD drawings and to the fabricated parts which can again be used to validate simulation results of the molding process.

Another extremely powerful capability of the technique is to use the volumetric data together with the contrasts that are due to differences in atomic mass of the analysed materials. This combined with image analysis techniques, features having different contrasts can be segmented, allowing for individual analysis of single features or for statistical analysis of distributions and orientations etc. The segments can meshed and exported in standard 3D formats for further processing, such as 3D printing.

At IPU, we are very happy to see a current expansion of our collaboration with DTU 3D Imaging Center in order to provide services of advanced imaging techniques to the industry. Our collaboration with the center allows flexible access to the state of art instruments and competences at the center, on commercial terms, and in a way that fits well with the industrial projects conducted at IPU.
