Technical Examples
  1. A method for detecting and attenuating grid artifacts in a digital radiographic image comprising; providing an input digital radiographic image; processing the input digital radiographic image with a detection algorithm based on 2-D dynamic correlation in both spatial and frequency domains to determine whether the input digital radiographic image has a grid artifacts; and if it does detecting the grid orientation, frequency, and signal-to-noise ratio of the grid artifacts, designing a frequency bandstop (notch) digital 1-D filter as a function of the grid frequency and attenuation level; and suppressing the grid artifacts by further processing said input digital radiographic image with said designed filter to produce an output digital radiographic image of improved image quality.
