Abstract
A technique is disclosed for generating a new contour and/or a 3D surface from contour data using a surface displacement field. The technique is preferably applied to un-contoured target images within a 4D image sequence for which contour data is desired. The technique can be initialized with contour data related to a reference image that has already been contoured, e.g. by a doctor who manually enters contour information into a computer. Image registration (calculation of correspondence between the reference image and target image) can be performed simultaneously with segmentation (identifying regions of interest in the target image). This allows one to make use of segmentation information in a reference image to improve the accuracy of contouring within the target image.
