Registration of 3-D multimodality brain images by curve matching
The 3D multimodality brain image registration algorithm proposed here is based on the matching of feature curves which are defined by the intersections of the interhemispherical fissure plane (IFP) and the skull surface. The IFP as detected by a principal axes technique while the skull boundary in each scan is extracted by tracing the outermost closed contour. The feature curves care rotated to lie on 3D planes which are parallel to each other so that the problem is reduced to a 2D curve matching task. An MRI-PET image registration result is presented.<<ETX>>
