  • Fourier and spline-based reconstruction of helical CT images
    Patent number: 6272200
    Abstract: A method and apparatus are provided for reconstructing a set of CT images from helical CT data. The method includes the steps of receiving the helical CT data and generating a set of fan-beam sinograms at equally spaced longitudinal positions. The method further includes the steps of estimating a set of parallel-beam sinograms from the generated set of fan-beam sinograms and reconstructing the CT images using a parallel beam reconstruction algorithm.
