A PROPELLER based 3D Fast Field Echo (FFE) sequence and reconstruction method for free-breathing data acquisition in dynamic abdominal imaging is studied. The proposed method acquires 3D blades dynamically depending on the physiology property. Two weighting functions are proposed to preferentially use the preferred data in the gridding process and reconstruction. Experimental results demonstrate that the proposed method is able to reduce respiration artifacts and sharpen images.
