Abstract :
A new method for optimizing the performance of CT and MRI head registration techniques introducing elastic deformation is presented. The method uses a Self Organizing Map to define the node correspondence of the triangulated external surfaces of both modalities. The two sets of equivalent nodes are subsequently registered using Thin-Plate Splines deformation
