Abstract
In this paper, a Feldkamp-type approximate algorithm is proposed for helical multislice Computed Tomography (CT) image reconstruction. For reconstruction of practically required planar transversal image slices, the algorithm proposes a new short scan helical trajectory which satisfies Tuy’s exact reconstruction condition. A planar slice reconstructed using this new trajectory has potential to be exactly reconstructed. This method improves the approximate helical reconstruction in terms of artifacts reduction and efficiency enhancement.
