Claim Text:
1. A method comprising: computing a deformation vector field (DVF) relatively spatially registering first and second images; adapting a contour delineating a structure in the first image using the DVF to generate an initial contour for the structure in the second image; receiving a final contour for the structure in the second image; and correcting the DVF based on the initial and final contours for the structure in the second image to generate a corrected DVF; wherein the computing, adapting, and correcting are performed by an electronic processing device; and wherein the correcting comprises: computing an adjustment deformation vector field (adjustment DVF) relating the initial and final contours for the structure in the second image; and combining the DVF and the adjustment DVF to generate the corrected DVF.
