Abstract
We demonstrate a comprehensive image processing system to automatically detect the use of a stationary anti-scatter device (also referred to as a linear grid) and suppress the artifacts that such a device creates in a digital radiographic images. The detection process consists of the stages of determining an appropriate region of the image from which to perform the analysis; performing a spectral analysis to identify the grid frequencies; and identifying the most likely grid line frequency. When a grid is detected, the results of the detection process are used to perform adaptive grid suppression using custom designed blurring filters and a plurality of adaptation methods.
