An autofocusing nonrigid respiratory motion correction
method for abdominal imaging was developed. This
technique used motion trajectory candidates estimated
from 3D image-based navigators that were acquired with a
variable-density 3D cones trajectory. The performance of
the proposed autofocusing motion correction was
demonstrated with free-breathing scans of the abdominal
vasculature.
