FIGURE 3

Phantom model consisting of a static object and a moving object sitting atop a balloon that was inflated and deflated with water. Full FOV PROPELLER image during stationary conditions (A) compared with full FOV PROPELLER image during object motion without (B) and with self-navigated motion correction (C). Inset magnified images demonstrate distortion and blurring of both moving (D) and static objects (E) within the motion-corrected full FOV images. Motion-corrected 1/2 FOV (dashed box in B) targeted-PROPELLER images separately targeting the moving (F, with same FOV magnified in G) and static (H) objects. Notice that moving and static objects were both blurred and distorted in the motion-corrected full FOV image (C–E), whereas motion of the moving object was effectively corrected in 1/2 FOV targeted-PROPELLER image targeting the moving object (F, G) with no impact on the static object image (H).
