Industrial X-ray tomography, also called CT for Computed Tomography, is a non-destructive imaging and
testing technique that provides a three-dimensional (3D) representation of the inside of a part or material.During a
CT acquisition, the part is placed on a rotation stage that makes one or more full turns. The machine, the X-ray source, and the acquisition parameters are controlled by the X-Act software. As the part rotates, a series of radiographic projections is acquired from different angles.
All of these projections are then used in the
reconstruction step to generate a complete 3D volume of the part. This step is also carried out with X-Act, which now has a section specifically dedicated to the reconstruction of tomographic data. Once the volume is obtained, it becomes possible to navigate through it, make virtual cuts, and use post-processing software to extract the information you are looking for:
internal defects, dimensional data, material characteristics, assembly analysis, or comparison with a CAD model.
