Example cross-sectional images from the starting (left column) and target
(middle column) 3D images for all four tumor cases are compared to the deformed images
obtained via the optimal parameter values (right column). Rows 1-4 are for DC1, DC2,
DC3, and HC, respectively. Tumors in the dog cases are painted white in order to aid visual
comparison to the gadolinium-enhanced final images. For HC, the tumor is assigned black.
