PROBLEM TO BE SOLVED: To improve diagnostic accuracy based on an analysis result of a dynamic phase image.SOLUTION: A dynamic phase analysis system 100 is configured so that: a control unit 21 of a console 2 performs attenuation processing of an image signal component by an artifact to plural frame images which indicate a dynamic phase of a subject created by cooperation between a radiation generator 1 and an FPD cassette 4, and analyzes a dynamic phase of the subject on the basis of the plural frame images subjected to the attenuation processing.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】動態画像の解析結果に基づく診断精度を向上させる。【解決手段】動態解析システム１００によれば、コンソール２の制御部２１は、放射線発生装置１とＦＰＤカセッテ４の協働により生成された被写体の動態を示す複数のフレーム画像から人工物による画像信号成分を減弱処理し、減弱処理後の複数のフレーム画像に基づいて、被写体の動態を解析する。【選択図】図５
