Industrial Computed Tomography
Look inside your components with 3d computed tomography
Many defects in components, such as shrinkage cavities, pores or inclusions cannot be seen from the exterior and are therefore difficult to verify during conventional quality control. Nevertheless, they can cause serious defects with catastrophic consequences. 3D computed tomography reliably detects these defects. With our practical test reports we provide you a tool with which you can efficiently find the cause.

How does 3d computed tomography work?
From the x-ray image to the 3d model
Industrial computed tomography provides three-dimensional images that make visible the structures inside a component scanned. For the 3D model, first a series of two-dimensional X-ray images are prepared from various angles and virtual sections of the component calculated from these images. These sections are in turn reconstructed to produce a virtual 3D volume. The data generated are then prepared using a special software application which makes possible numerous uses, e.g. assessment of the dimensional accuracy, analysis of defects and flaws or feedback into a CAD model. We undertake the evaluation using VGStudio MAX and GOM Inspect Professional.
What are the most important ct scanning methods?
There are two basic CT methods, specifically the cone beam method and the fan beam method. We have a comprehensive range of equipment for 3D computed tomography for all power classes up to 450 kV and offer both scanning methods. We use these methods to analyse vary small components as well as for large items with a diameter of up to 550 mm and a height of up to 1,200 mm.
Cone beam method
In the cone beam method the conical X-rays are acquired by a digital flat-panel detector after passing through the component. The fast cone beam method permits shorter measuring times and is particularly suitable for smaller components for the three-dimensional depiction of internal structures and for the detection of flaws.
Technical equipment:
- ZEISS Metrotom 800 (225 kV, 3D CT)
- GE v | tome | x M (300 kV, 3D CT)
- GE microme | x (180 kV, 2D X-ray)
- GE nanotom m (180 kV, 3D CT)
Fan beam method
In the fan beam method the fan-shaped X-rays are acquired by a line detector after passing through the component. During this process, individual cross-sections are obtained that yield a 3D volume by means of vertical stitching or by stacking the layers. The fan beam method is particularly suitable for large components and components with thick walls, e.g. cylinder blocks, for defect inspection and for measuring dimensions.

Frequently asked questions about 3d computed tomography
Which defects can be found with the aid of 3d computed tomography?
3D computed tomography (3D CT) is excellently suited to the detection of component defects that are not visible from the exterior, for instance shrinkage cavities, pores or inclusions, even cracks or residues such as metal powder can be detected reliably. For this reason 3D CT is also often used for the inspection of castings.
How is 3d computed tomography used in industry?
As part of industrial computed tomography, 3D CT makes it possible to undertake not only exact measurements (e.g. of the wall thickness) on the object inspected, it also allows us to compare the results of the 3D measurement directly with the CAD data (preparation of nominal-actual comparisons).
What are the advantages of 3d computed tomography?
By preparing a three-dimensional model, the structures inside the component can be acquired holistically and clearly, unlike, for example, in optical metrology. Defects, shrinkage cavities, inclusions, pores and much more are not only detected more easily, they can also be located precisely.
Furthermore, measurements that would be very difficult to make on the real component can be undertaken straightforwardly on the 3D model. This aspect relates, e.g. to wall thickness analysis or the measurement of internal volumes.
