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.
