PROBLEM TO BE SOLVED: To diagnose a greater number of subjects in a short period by utilizing frame images obtained by dynamic state radiography in mass examination to examine/diagnose many subjects at a time.;SOLUTION: A control part of an analysis WS divides each of a series of frame images obtained by radiographing the dynamic state of a subject into a plurality of blocks composed of a plurality of pixels corresponding to one another at the same position, calculates the feature amount related to the dynamic state of the subject in each block based on a signal value of pixels in the block within a target area for analysis in the plurality of frame images, and discriminates between a normal dynamic state and a suspected abnormal dynamic state of the subject based on the calculated feature amount. Then, the control part redivides a block discriminated as the suspected abnormal block into a plurality of minor blocks composed of a smaller number of pixels than the number of pixels included in the block, and calculates the feature amount related to the dynamic state of the subject in each minor block based on a signal value of pixels in each redivided minor block to generate diagnosis support information.;COPYRIGHT: (C)2013,JPO&INPIT
