Brain image registration based on curve mapping
Christos A. Davatzikos, Jerry L. Prince · 2002
A new two-stage approach for brain image registration is proposed. In the first stage, an active contour algorithm is used to establish a length-preserving, one-to-one mapping between the cortical and the ventricular boundaries in the two images to be registered. This mapping is used in the second step by a two-dimensional transformation which is based on an elastic body deformation. This method was tested by registering magnetic resonance images to both photographic pathology images and atlas images.>
