Figure 6.

The top and bottom rows show two short-axis slices for NCAT config II with 2 cm motion including drift. Slices in column (a) are reference, (b) are with motion but no correction, and (c) are with motion correction. In the top row, notice the reduction in the respiratory-motion-induced artifactual cooling of the heart after motion correction. In the bottom row, notice the reduction of the artifactual appearance, clearer visibility of lesion, better separation from the liver, and thinner appearance of the heart wall with correction. We did not use any postreconstruction smoothing so as to more clearly present the impact of respiratory motion and its correction on the images.
