Vessel to Image Registration using Rigid and Elastic Transformations
Julien Jomier, Stephen Aylward · 2003
Abstract. Several recent studies demonstrate a real potential in taking tubular structures as a base for image registration. In this paper, we present a novel technique to conduct deformations on tubular structures. Our approach aligns a pre-extracted tubular model, e.g. vessels inside an organ or a set of bones, with an image by combining both rigid and elastic transformations. The physical structure and properties of the tubes are taken into account to drive the registration process. This model to image registration shows sub-voxel accuracy as well as robustness to noise and a convergence time of less than one minute. 1
