A system and method of placing constraints on a deformation map. The
method includes the acts of generating a deformation map between two
images, identifying a defined structure in one of the images, applying
the deformation map to relate the defined structure from the one image
onto the other image to create a deformation-based defined structure,
modifying the deformation-based defined structure, and updating the
deformation map in response to the step of modifying the
deformation-based defined structure.
