摘要

A radiographic moving image processing device comprises: an image information generation unit which generates still image information for one frame on the basis of a tone signal that is generated in response to the amount of radiation receipt by each pixel, and combines multiple pieces of still image information for multiple frames continuously to generate moving image information; a detection unit which detects a structure of interest on the basis of the still image information for each frame in the moving image information; and a region-of-interest setting unit which calculates the difference between frames with respect to the structure, sets the structure for which the calculated difference is equal to or higher than a predetermined value as a region-of-interest, and, when there are multiple structures each having a value equal to or higher than the predetermined value or a structure having a value equal to or higher than the predetermined value is newly detected while setting the region-of-interest, sets the multiple structures each having a value equal to or higher than the predetermined values as the region-of-interests.
