CT/US segmentation-less registration
Chantal Müller · 2007
CT is a frequently used imaging diagnostic modality; US enables real-time, non invasive, intra-operative visualization of mobile and deformable organs. We have developed a CT/US 3D/3D rigid voxel-based registration method avoiding segmentation of US images enabling intra-operative transfer of planning data and guidance. Image pre-processing is necessary to make the modalities as close as possible (filtering, interface enhancing in CT data, filtering, artefact and acoustic shadow removal in (...)
