Patent ID: 8885909

Claim:
A radiographic image processing apparatus which performs image processing on pieces of image data of radiation detection elements captured by a radiographic image capturing apparatus, wherein the radiographic image capturing apparatus comprises a detection unit in which radiology detection elements are arranged in a two dimensional manner, the radiology detection elements being provided respectively in sections which are sectioned by a plurality of scanning lines and a plurality of signal lines arranged so as to intersect each other, the radiographic image processing apparatus comprising: a dividing unit which divides a region in section areas by sectioning the region, in which the pieces of image data are arranged in a two dimensional manner, in units of a predetermined number of pieces of image data at least in an extending direction of the scanning line on the detection unit when the pieces of image data are arranged in a two dimensional manner so as to correspond respectively with the plurality of radiation detection elements arranged in a two dimensional manner; an average value calculation unit which performs a calculation of an average value of the pieces of image data aligned in the extending direction of a same scanning line among the pieces of image data in a section area for each of the scanning lines for each of the section areas; an edge compression unit which generates a profile in which a difference in average values of the pieces of image data which occurs at a border of a captured subject and a surrounding thereof is compressed for each of the section areas with respect to a signal line extending direction profile of the average values of the pieces of image data of individual scanning lines calculated for each of the section areas; a filter processing unit which performs processing to apply an adaptive filter to the profile in which the differences are compressed for each of the section areas; and a correction data generation unit which generates pieces of correction data arranged in a two dimensional manner by reconstructing pieces of data at other positions in the region based on pieces of data in the profiles to which the adaptive filter is applied, wherein pieces of image data in which noises are removed are generated respectively for the radiation detection elements by subtracting the pieces of correction data of corresponding positions from the pieces of image data arranged in a two dimensional manner, respectively.
