The present invention relates to an abdominal phantom device for dynamic image registration based on breathing exercises which comprises: a base formed in a flat board and mounted on the upper portion of a bed of a medical imaging system； a holder part arranged slidably in the front-rear direction on the upper portion of the base, in which a plurality of mounting grooves are formed； a plurality of sample cases inserted and installed into each mounting groove of the holder part, in which reagent is filled inside； a driving cylinder installed in the base, with the rod end connected to the holder part, which generates a driving force to make the holder part move reciprocating in the front-rear direction on the base； and a control part connected to the driving cylinder, which controls the hydraulic supply of the driving cylinder and controls the operation of the driving cylinder and controls the movement of the holder part arranged in the upper portion of the base. In the abdominal phantom device for dynamic image registration based on breathing exercises, the holder part is installed to be moved in the front-rear direction on the base, and a sample case is installed in the holder part, which simulates an organ making movement according to the body&prime；s breathing exercises. Thus, while the driving cylinder and the control part make the holder part move reciprocating in the front-rear direction during imaging by the medical imaging apparatus, the image signal strength for each sample case allows to grasp the influence of the image by the movement similar to the breathing exercises of a body organ.본 발명은, 의료용 영상촬영장치의 베드 상부에 안착 배치되는 판 형상의 베이스, 베이스의 상부에 전후방향으로 슬라이딩 가능하게 배치되며, 복수의 안착홈이 형성된 홀더부, 홀더부의 각 안착홈에 삽입 설치되며, 내부에는 시약이 채워지는 복수의 샘플케이스, 베이스에 설치된 상태로 로드 단부가 홀더부와 연결되어, 홀더부가 베이스 상에서 전후방향으로 왕복이동되게 구동력을 발생시키는 구동실린더, 구동실린더와 연결되어, 구동실린더의 유압 공급을 조절하며 구동실린더의 작동을 제어하면서 베이스 상부에 배치된 홀더부의 이동을 조절하는 제어부를 포함하는 호흡운동에 따른 동적영상 정합용 복부 팬텀장치를 제공한다.이와 같은, 호흡운동에 따른 동적영상 정합용 복부 팬텀장치는, 베이스
