Verfahren zur markerlosen Navigation in präoperativen 3D-Bildern unter Verwendung eines intraoperativ gewonnenen 3D-C-Bogen-Bildes

摘要

The method involves taking an intra-operative 3D image with a C-curve, registering the medical instrument in relation to the image so that a registering matrix MDN is obtained, registering the intra operative image in relation to a current pre-operative 3D image so that a registering matrix MED is obtained and then navigating the medical instrument in the pre-operative image.
