Query: Cortical Surface Co-Registration based on MRI Images and Photos   Brain shift, i.e. the change in configuration of the brain after opening the
dura mater, is a key problem in neuronavigation. We present an approach to
co-register intra-operative microscope images with pre-operative MRI to adapt
and optimize intra-operative neuronavigation. The tools are a robust
classification of sulci on MRI extracted cortical surfaces, guided user marking
of most prominent sulci on a microscope image, and the actual variational
registration method with a fidelity energy for 3D deformations of the cortical
surface combined with a higher order, linear elastica type prior energy.
Furthermore, the actual registration is validated on an artificial testbed with
known ground truth deformation and on real data of a neuro clinical patient.
