1. A method for contouring a medical image, comprising:
- receiving a plurality of source images, wherein each source image of the plurality of source images is associated with a respective contour identifying one or more features of the source images;
generating deformation data for each source image, of the plurality of source images, to a target image;
generating a plurality of candidate contours for the target image based on the deformation data and respective contours associated with each source image of the plurality of source images; and
generating a target contour for the target image based on the plurality of candidate contours.

Abstract
Systems and methods are provided for contouring a set of medical images. Deformation field data is generated between a source image and a target image of the set of medical images. The deformation field data relates structures in the source image to corresponding structures in the target image and is generated in accordance with a deformable registration algorithm. The deformation field data is utilized to generate target contour data associated with the target image from source contour data, associated with the source image, that identifies one or more objects within the source image.
