Paper Abstract

Finite-size X-ray sources degrade the radiologic image by attenuating the high-frequency components of the image and by phase distorting a significant number of these frequencies. Coherent-optical spatial filtering was employed to correct these distortions in the Fourier transform of the radiologic image. This included the use of amplitude-only and amplitude-and-phase (holographic) filters. The contrast and resolution of X-ray images were improved.
