Title:
SYSTEM AND METHOD FOR REDUCING ARTIFACTS IN MOTION CORRECTED DYNAMIC IMAGE SEQUENCES
Document Type and Number:
WIPO Patent Application WO2006107801
Kind Code:
A3
Abstract:
A system and method for reducing artifacts in a motion corrected image sequence are provided. A method for reducing an artifact in a motion corrected image sequence comprises: applying a deformation to a reference image of a plurality of post-contrast enhanced images to obtain an interpolated version of the reference image (340); and performing a registration between the interpolated version of the reference image and a pre-contrast enhanced image and the plurality of post-contrast enhanced images to obtain a plurality of motion corrected images (350).
