1. A method of contouring a three-dimensional (3D) medical image, comprising:
- receiving a source image slice, from a set of two-dimensional (2D) image slices constituting the 3D medical image, and source contour data identifying one or more objects within the source image slice;
receiving a selection of a target image slice, from the set of the 2D image slices;
generating deformation field data from the source image slice and the target image slice in accordance with a deformable registration algorithm, the deformation field data correlates locations in the source image slice to related locations in the target image slice; and
generating target contour data that identifies the one or more objects within the target image slice based on the source contour data and the deformation field data.

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.
