Abstract
A prospective navigator algorithm with a dual acceptance window (DAW) technique was developed to reduce image artifacts induced by respiratory motion without increasing imaging time. A phantom study shows that the ghost level measured by ghost-to-image ratio was reduced by 27.1% (p < 0.005) using the DAW technique compared to the conventional single acceptance window technique. This DAW technique can also be used to reduce imaging time while maintaining comparable ghosting level.
