Abstract
Computed tomography (CT) with X- and Gamma-rays is a well-known imaging method, established first for medical use. Applications to non-destructive testing were published in the early 1980s. CT offers the possibility to map non-invasively the three-dimensional local absorption of X-rays of samples and components, which correspond to the inner and outer structures. The result of a CT measurement is usually given in the form of a 3D image matrix. Each point represents a single volume element in the sample, a voxel. CT delivers an absolute measure, the linear attenuation coefficient μ, for the absorbed X-ray radiation averaged over one voxel.
