  • Method for producing tomographic images using direct Fourier inversion
    Patent number: 4991093
    Abstract: The present invention is a method for examining at least a portion of an object using penetration radiation. The method includes the steps of transmitting radiation from an external source through the object in a plurality of coplanar rays, detecting the attenuated transmitted radiation after it has passed through the object, determining the projection data for said rays, and inverting said projection data to generate the distribution of the attenuation coefficient, wherein said inverting step includes the Direct Fourier Inversion Method such that the projection data is padded and the Fourier coefficients are filtered.
