Visualization software for CT: fan/cone beam and metrology applications

This paper presents the high-performance capabilities developed in specific software for industrial computed tomography (CT) applications. The Technology Center AIMEN has developed in the last years a computed tomography system, in collaboration with the USC, for non-destructive testing and metrology purposes. A visualization tool was implemented for the CT system including 3D rendering and image reconstruction, following the continuous evolution of the system. Image reconstruction accounted for the system’s initial fan beam geometry, based on filtered backprojection algorithm. Further development of the CT system with a flat panel detector needed a reconstruction tool for cone beam geometry.
