PROBLEM TO BE SOLVED: To make it possible to provide diagnosis support information with blood flow condition resulting from breathing taken into consideration.SOLUTION: A photographing apparatus 1 dynamically photographs the chest under breathing condition and acquires a plurality of frame images showing the dynamic state of the chest. An arithmetic device 4 determines one of the plurality of acquired frame images to be a reference image, extracts a lung field area in the reference image, divides the extracted lung field area into a plurality of small areas, and then calculates, in another frame image of the plurality of acquired frame images, small areas corresponding respectively to each small area of the reference image. The arithmetic device 4 performs image analysis for each corresponding small area in the plurality of frame images, and determines for each of the small areas whether or not the blood flow condition is abnormal. |
