....In order to obtain a unique solution for finite element equations, at least one boundary condition must be supplied. The implemented boundary conditions modify the stiffness matrix and make it nonsingular. There are multiple ways of implementing boundary conditions as discussed in the literature [23]. The easiest way to implement the boundary conditions is to modify the diagonal elements of the matrix and the rows of the force vector at which the boundary conditions will be applied. In our model, one end of the cystic was fixed, which implied zero displacements for the associated fixed nodes. ....

....Horowitz [72] Nastar and Ayache [53] This approach is similar to the deformable Fourier model except that both the basis functions and the nominal values of their coefficients are derived from a template object shape. Deformable models based on modal analysis use the theory of finite elements [73]. An object is assumed to be represented by a finite set of elements whose positions are defined by the positions of n nodes, which are points in d dimensional space. The node positions can be stacked into a vector X , which has length nd, and element interpolation characterizes the complete ....

....scheme used for the unknown coecients of u. To calculate the deformation of an anatomical structure given a set of spatial correspondences between images, these correspondences must be integrated into the linear equation system. To this end, we use the procedure described in Huebner et al. [22] and Peckar et al. 23] Since a value for the unknown u j is given through the established correspondences, u j can be incorporated into the linear equation system by a subtraction of the product u j A j , where A j denotes the j th column of the sti ness matrix A, from the righthand side vector ....
