Abstract

The aim of our work is to improve data analysis in thoracic oncology applications by means of non-rigid registration of CT and PET images. A mutual information-driven transformation using B-spline free-form deformations performs the alignment of the image volumes. Special constraints relying on hierarchically identifying corresponding structures in both modalities have been added to guarantee the convergence towards an optimal registration.
