Industrial Applications

X-ray computed tomography is the method of using X-ray radiation to take a number of two dimensional images of an object in many positions around an axis of rotation. From these images, using software, a three dimensional (3D) model of the object’s external as well as internal structure is reconstructed and can be analyzed. Typical areas of use for CT in industry are in the detection of weakness points such as voids and cracks, and particle analysis in materials.

As such, it is the only technology for industrial quality control of workpieces having non-accessible internal features (e.g. components produced by additive manufacturing) or multi-material components (e.g. two-component injection molded plastic parts or plastic parts with metallic inserts).

The number of industrial applications of CT is large and rapidly increasing. We describe here a survey of application examples from the manufacturing industry as well as from other industries, e.g. electrical and electronic devices, inhomogeneous materials, and from the food industry.

Synchrotrons sources offer specific advantages for the use of X-ray computed tomography. This form of radiation has several relevant properties: monochromaticity, high spatial coherence, high collimation, high brightness and intensity, low emittance, and wide tunability in energy/ wavelength.

Phase contrast imaging can be used to visualize small details and increase image contrast within structures that otherwise would appear uniform. Phase contrast imaging differentiates between structures under analysis by exploiting differences in the refractive index of materials and highlighting small details of differing refractive index.
