FFT-based approach to longitudinal interpolation in single- and multi-slice helical CT

Presents an approach to single- and multi-slice helical computed tomography (CT) image reconstruction that exploits the fast Fourier transform (FFT) and the Fourier shift theorem to generate from the helical projection data a set of fan-beam sinograms corresponding to equispaced transverse slices.
