An own-developed CT/DR system for visualization and defect recognition in NDT

We have developed an industrial X-ray computed tomography system that also provides digital radiography images (CT/DR) for dimensional and general non-destructive testing inspection in AIMEN, in collaboration with the University of Santiago de Compostela (Spain). The system, fully operational at 2009, includes a detector array of 1280 active elements with submillimetrical spacing, together with a 225 kV mini-focus tube, integrated in a 3-axis positioning system of flexible configuration. The total length of the detector is 1 m. Some of the most remarkable features of the system are the image variable magnification and the capability of capturing both tomographic and radiographic images. Specific software is being developed for visualization and automated defect recognition of the acquired images. The software accomplishes visualization and automated analysis for radiographs, sinograms and CT reconstructed images including the generation of 3D images from the CT slices.
