Paper Abstract
We consider the application of various low-pass (noise reduction and/or smoothing) and high-pass (image restoration/enhancement) filters to reconstructed CT images. Limitations of some traditional smoothing filters are described and modified filters which overcome these disadvantages are presented. A second class of filter attempts to compensate for image degradation effects introduced by the system transfer function (influenced primarily by detector and source aperture sizes). We specifically investigate the Wiener filter as a convenient means of implementing the image restoration procedure.
