ABSTRACT:
Distortion is reduced in images derived by Fourier transform methods from projection samples by manipulating the Fourier transformed values by a predetermined procedure of a kind that subjects the image values to unwanted distortion, and then applying to the projection samples or image values a correction function that corresponds to the predefined procedure.
