Abstract
A three-dimensional model of a reconstructed bone framework is obtained using an iterative, surface interpolating algorithm. A reference and a target three-dimensional model are provided. The reference model is non-rigidly registered to the target model based upon positional constraints, so as to produce a registered reference model. An initial reconstructed model is set as the registered reference model. A first correspondence search is iteratively conducted to identify a first set of corresponding points on the reconstructed and target models. During each iteration, the reconstructed model is incrementally and non-rigidly registered to the target model based upon the corresponding points. A second correspondence search is conducted to identify a second set of corresponding points on the reconstructed and target models. Crossings in the identified corresponding points are removed and the reconstructed model is non-rigidly registered to the target model, based upon the remaining corresponding points so as to produce a registered, fully reconstructed model. The preferred embodiment is the reconstruction of a skull using Laplacian deformation method with flip-avoiding interpolating s…
