Abstract
A method for detection, quantification, and visualization of brain shift in serial MR and CT images is presented. The method consists of three steps. It first establishes correspondence between a number of point landmarks in the images. It then uses the correspondences to determine a transformation function that warps one image to the geometry of the other. It finally uses the obtained transformation to create a vector flow that represents the local motion or deformation of one image with respect to the other. The method does not require the solution of a system of equations and, therefore, is especially effective when a large number of correspondences is needed to represent complex brain deformations.
