Paper Abstract

In this paper, a Feldkamp-type approximate algorithm is proposed for helical multislice Computed Tomography (CT) image reconstruction. For a planar transversal reconstruction slice under consideration, the algorithm adopts a set of scanning data samples such that all points of the planar plane satisfy Tuy's exact reconstruction condition and, therefore, have potential to be exactly reconstructed. This can provide a practically feasible compromise between image quality and computation efficiency in the reconstruction. Simulation results can show advantages of this algorithm in reduction of artifacts and improvement of computational efficiency in comparison with the existing algorithms.
