Two-Stage Multimodality Medical Volume Registration

Abstract

A semi-automatic, two-stage multimodality medical volume registration is described. This registration hinges on surface matching by using 3D chamfer matching algorithm first and on global-information-based matching afterwards. Two stages are applied, because information contents of registered volumes are different and no single registration method works satisfactorily so far. This approach is applied to MRI (Magnetic Resonance Imaging), CT (Computed Tomography) and SPECT (Single Photon Emission Computed Tomography) data volumes. Pilot experiments prove satisfactory results
