ABSTRACT:
Tomography apparatus is used to irradiate a body cross section and acquire a relatively small amount of data which is mapped into a two dimensional array or sinogram and image enhancement techniques are applied to the sinogram to reveal visible lines representing flaws. An array processor operates on the sinogram to perform edge enhancement and averaging convolutions, a fast Fourier transform, low pass filtering in frequency domain, and an inverse fast Fourier transform to generate the enhanced sinogram.
