Overview: This paper presents a composite method for landmark-guided surface matching and volumetric non-rigid registration, with an application to prostate biopsy. The two-step method, based primarily on finite element and thin-plate spline techniques, consists of a boundary matching process, followed by a volumetric warping step. In practice, the boundary matching method allows for registration of anatomical surfaces, such as prostate gland capsules, in a way that is bijective, i.e. one-to-one and onto. The novelty of this approach is that it allows for the exact matching of pre-specified corresponding landmark points on the two surfaces to be matched.
