Rezumat:

The computerized industrial tomography is one of the NDT methods entirely based on the computer reconstruction technique that offers very detailed 2D and 3D graphic images of the tested object. After a brief description of a simple laboratory tomograph, some important features of the software package, specially developed for tomographic analysis, have been presented. Some relevant 2D and 3D tomograms as well as some considerations regarding the material identification from tomograms are showed in the last part. The Filtered Back Projection based algorithm for reconstructing the 2D tomograms and a direct representation of the 3D-matrix method for 3D tomograms were employed.
