Summary:To correctly perform medical followup using radiographic images to be diagnosed and past radiographic images to be compared with even when the radiographic images are dynamic images.SOLUTION: A dynamic image analysis system 100 comprises: image generation means for generating dynamic images consisting of a plurality of frame images showing the dynamics of a subject; first and second signal value detecting means for detecting a first signal value of a first predetermined region and a second signal value of a second predetermined region in the frame images of generated first and second dynamic images; image processing condition determination means for determining image processing conditions for bringing the signal value of the first predetermined region in the first dynamic image closer to the signal value of the second predetermined region in the second dynamic image, on the basis of the detected first and second signal values; and image processing means for performing image processing on the first dynamic image under the determined image processing conditions to generate a processed dynamic image.SELECTED DRAWING: Figure 6 【課題】診断対象の放射線画像と比較対象の過去の放射線画像とを用いた経過観察を、放射線画像が動態画像の場合であっても正確に行うことができるようにする。【解決手段】動態画像解析システム100は、被写体の動態を示す複数のフレーム画像からなる動態画像を生成する画像生成手段と、生成した第一,第二動態画像のフレーム画像における第一所定領域の第一信号値、第二所定領域の第二信号値を検出する第一,第二信号値検出手段と、検出した第一信号値及び第二信号値に基づいて、第一動態画像における第一所定領域の信号値を第二動態画像の第二所定領域における信号値に近づけるための画像処理条件を決定する画像処理条件決定手段と、決定した画像処理条件にて第一動態画像に画像処理を施して処理済み動態画像を生成する画像処理手段と、を備える。【選択図】図6
