Automatic registration of MRI head volumes using an octree anatomical atlas

We describe a method for the automatic registration of transversal MRI-head-volumes. Under automatic registration we understand the determination of an adequate coordinate system for a specific head volume, which is adapted to this particular head, describing the position, direction and size of the head in the respective MRI-volume. After determining the coordinate system the specific head volumes are mapped against a model of an anatomical atlas.
