Fan/cone beam CT: visualisation and applications for non-clinical X-ray imaging

Computed tomography (CT) for non-clinical applications is constantly evolving in many different fields, from industry, laboratory and metrology applications. The Technological Center AIMEN, in collaboration with the University of Santiago de Compostela, has implemented a dual-detector computed tomography system. A specific visualisation tool has been developed including 3D rendering and image reconstruction, following the modular capabilities of the CT system. Software capabilities include CT reconstruction for different geometries, special filtering, higher computer memory requirements, basic knowledge extraction, etc., resulting in flexible software with possibilities for further applications development. This new tool is adapted to the emerging needs of an open CT system which is built in a modular configuration to answer new challenges, as those for dimensional metrology (improving its spatial resolution and image quality) and specific analysis for non-destructive testing.
