Title:
RADIOGRAPHIC-IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/145377
Kind Code:
A1
Abstract:
Disclosed is a radiographic-image processing device that can accurately remove striated artifacts superimposed onto image data taken by an FPD radiographic imaging device. Said radiographic-image processing device (70) is provided with: a partitioning means (71) that partitions a region (Q), in which image data (D) taken by a radiographic imaging device (1) is arranged two-dimensionally, into segments (Sk); a mean-value computation means (72) that computes mean values (Da(n)) from image data (D) along the same scanline (5) in each segment (Sk); an edge compression means (73) that compresses mean-value (Da(n)) differentials in boundary regions between the subject that was imaged and the surroundings thereof; a filtering means (74) that applies an adaptive filter to the differential-compressed profile; and a correction-data creation means (75) that creates correction data (Ds) on the basis of each datum (ds(n)) in the adaptive-filtered profile. Denoised image data (D*) is generated by subtracting corresponding correction data (Ds) from the image data (D).
