Self-calibration for a multi-segment straight-line trajectory CT using invariant moment

SPIE Proceedings, 2012
Multi-segment straight-line trajectory computed tomography (CT) requires accurate movement between each segment trajectories. In industrial applications for large objects, it is difficult and very cost-expensive for the mechanical and control system to ensure the accurate movement during the rotation process between two segment trajectories.
