Abstract:
A medical diagnostic imaging apparatus including an upstream rasterized imaging processor that generates rasterized uncorrected image data, and a processing means for generating corrected image data from the rasterized uncorrected diagnostic image data, the processing means being programmed to:a) filter the uncorrected diagnostic image data to generate noise image data; b) determine statistical data from a first subset of the noise image data, the determining including: determining integration values for each of a plurality of raster line segments within a region of interest, determining an average integration value for the region of interest, and determining a line noise amplitude factor for a selected raster line segment within the region of interest based on the integration value of the selected raster line segment and the average integration value; and c) correct a second subset of the uncorrected diagnostic image data based on the statistical data, the second subset of the uncorrected diagnostic image data corresponding to the first subset of the noise image data.
