Abstract - Landmark-Free Initialization of Multi-Modal Image Registration.

To achieve convergence, nonlinear deformable image registration tasks of partial-view 3D ultrasound and MRI, as often seen in US guided interventions or retrospective studies thereof, need to be initialized. In clinical practice corresponding 3D landmarks are selected in both images. Performing this depends on the geometrical understanding of the targeted anatomy and the modality-specific appearance and is thus prone to error.
