Abstract EN
In industrial computed tomography (CT), it is often required to inspect large objects whose size is beyond a reconstructed field of view (FOV).
Some multiscan modes have been developed to acquire the complete CT projection data for a larger object using small panel detectors.
In this paper, we give a non-concyclic dual-source circular cone-beam scanning geometry based on the idea of multiscan modes and propose a backprojection-filtration-based (BPF) reconstruction algorithm without data rebinning.
Since the FOV calculated according to this nonconcyclic dual-source circular CT scanning geometry is larger than cardiac dual-source CT scanning geometry, our method can reconstruct larger horizontal slices (i.e., the slices perpendicular to rotation axis) than cardiac dual-source CT.
The quality of CT images is expected to be superior to those obtained using larger panel detectors.
The simulation results have indicated that CT images obtained by the proposed method are satisfying.
