Abstract
A radiographic image processing device includes a radiographic image acquisition unit that acquires a radiographic image taken from a subject using radiation, a region discrimination unit that discriminates a plurality of regions using the radiographic image, a scattered radiation component-estimation section that estimates scattered radiation components of the radiation of each region using scattered radiation component-estimation processing varying for each region, a scattered radiation component-subtraction section that subtracts the scattered radiation components of each region, and an image processing unit that generates a scattered radiation component-subtracted image where the scattered radiation components have been subtracted by sequentially estimating and subtracting the scattered radiation components of each region using the scattered radiation component-estimation section and the scattered radiation component-subtraction section.
