AEE for lesions. (a) The upper plot shows the AEE for different weights β. A large reduction of AEE with increasing weight β is observable for the lesion regions. (b) Same evaluation as in (a) but for registrations using a phantom without lesions. The reduction of average endpoint error is more pronounced when active lesions are present, indicating that it is the information by the lesions that leads to an improvement.
