  • Cone-beam reconstruction using backprojection of locally filtered projections and X-ray CT apparatus
    Patent number: 7477720
    Abstract: Embodiments of the present invention include a method and apparatus for accurate cone beam reconstruction with source positions on a curve (or set of curves). The inversion formulas employed by embodiments of the method of the present invention are based on first backprojecting a simple derivative in the projection space and then applying a Hilbert transform inversion in the image space.
