As as for this invention, precision is high, can obtain appropriate blood style analytical value, it designates that it is to obtain the image processing device whose it is possible to prevent the decrease of distinction efficiency of the thrombus due to movement diagnosis as purpose. The image processing device which does the blood style analyses which relate to this invention as for (3), the blood style control time decision processing which is decided the blood style control times which show the time which is supposed that the blood style of the object domain is controlled a state where the blood style of the object domain changes the dynamic picture image acquisition section which acquires the dynamic picture image which is formed from the plural frame pictures which were consecutively photographed to time direction (110) with, the breath information acquisition section which does the breath information acquisition processing which acquires the information of the breath which same period is done (120) with, attendant upon breath in the time where the frame picture was photographed (TC), on the basis of the information of breathThe blood style analytical amendment sections which do the blood style analysis contents amendment processing which makes blood style analytical criticality low the blood style control time decisive sections which are done (130) with, blood style control times (TC) the frame picture which was photographed, from the blood style analytical objects in comparison with the exclusion or other time zone (151) with, it has.本発明は、精度が高く、適切な血流解析値が得られるとともに、動態診断による血栓の判別性能の低下を防ぐことが可能な画像処理装置をえいることを目的とする。本発明に係る血流解析を行う画像処理装置(3)は、対象領域の血流が変化する状態を時間方向に順次に撮影された複数のフレーム画像から構成される動画像を取得する動画像取得部(110)と、フレーム画像が撮影された時刻に同期した呼吸情報を取得する呼吸情報取得処理を行う呼吸情報取得部(120)と、呼吸に伴い対象領域の血流が抑制されると想定される時刻を示す血流抑制時刻(TC)を、呼吸情報に基づいて決定する血流抑制時刻決定処理を行う血流抑制時刻決定部(130)と、血流抑制時刻(TC)に撮影されたフレーム画像を、血流解析対象から除外あるいは他の時間帯に比べ血流解析重要度を低くする血流解析内容補正処理を行う血流解析補正部(151)と、を備える。
