X-ray Computed Tomography Reconstruction on Non- Standard Trajectories for Robotized Inspection

Résumé

The inspection of complex industrial parts with X-ray computed tomography (CT) is of great interest to characterize them and detect potential flaws. Classically CT acquisition is based on a circular trajectory and this is by far the most frequent case in industrial applications. The use of robotic arms for inspection is recent and it is mainly done for accessing specific and difficult views in digital radiographic inspection. A new X-ray inspection platform is being installed at CEA LIST, which uses two robotic arms for positioning the X-ray source and the detector. In parallel to the development of this platform which enables a large variety of scanning trajectories, work will focus on developing CT reconstruction algorithms that are adapted to non-standard trajectories. We present here new challenges brought by these robotized inspections and preliminary results for reconstruction on such trajectories. CIVA software is used to simulate these complex inspections and our developed methods will be integrated as reconstruction tools.
