NDT: Tomography

X-Ray Computed Tomography (XCT) is the most suitable method for the study of the internal structure of material swith a high degree of detail, and with out the need of destroying the object. This technique can be applied to the characterization of many materials such as composites, metals and polymers.

During a tomographic evaluation, it is possible to evaluate defects, inclusions, damage,or the internal structure. Studies including metrological analysis and reverse engineer are also feasible, due to the potential of the technique to reveal the internal structure and surface of the inspected parts.

The technique is based on irradiating the object under study using an X-ray cone beam, while a detector collects radiation passing through the object. During the inspection, the part is rotated 360° under controlled conditions, and producing several projections for each angular position. For the case of large components, reduced angle inspections can be also performed. Large computing capacity is required for the generation and reconstruction of the recorded information.

Results can be displayed in cros ssections, or as a three dimensional views.
