Figure

FIG 1. Example of the deformation field inside a new lesion. All ar-rows point to the lesion center.
FIG 2. Example of the deformation field for 2 sections. The first image does not contain lesionsand presents large deformations with no clear sinking patterns, while in the second image with alesion, all the arrows inside the lesion point to the center.

FIG 4. Correlation between the number of ground truth lesions and the number of automatically detected ones (Pearson coefficient � 0.81, P �2.2688e-09).
