Endovascular navigation in patients: vessel-based registration of electromagnetic tracking to preoperative images

Erik Nypan,
Geir Arne Tangen,

et al.

Abstract: Electromagnetic tracking of instruments combined with preoperative images can supplement fluoroscopy for guiding endovascular aortic repair (EVAR). The aim of this study was to evaluate the in-vivo accuracy of a vessel-based registration algorithm for matching electromagnetically tracked positions of an endovascular instrument to preoperative computed tomography angiography. Five patients undergoing elective EVAR were included, and a clinically available semi-automatic 3D–3D registration algorithm, based on si… Show more
