Abstract EN
We present a novel method for nonrigid registration of 3D surfaces and images.
The method can be used to register surfaces by means of their distance images, or to register medical images directly.
It is formulated as a minimization problem of a sum of several terms representing the desired properties of a registration result: smoothness, volume preservation, matching of the surface, its curvature, and possible other feature images, as well as consistency with previous registration results of similar objects, represented by a statistical deformation model.
While most of these concepts are already known, we present a coherent continuous formulation of these constraints, including the statistical deformation model.
This continuous formulation renders the registration method independent of its discretization.
The finite element discretization we present is, while independent of the registration functional, the second main contribution of this paper.
The local discontinuous Galerkin method has not previously been used in image registration, and it provides an efficient and general framework to discretize each of the terms of our functional.
Computational efficiency and modest memory consumption are achieved thanks to parallelization and locally adaptive mesh refinement.
This allows for the first time the use of otherwise prohibitively large 3D statistical deformation models.
