Registration method for displaying electromagnetically tracked devices in fluoroscopic images

摘要

Visualization of electromagnetically tracked instruments in pre- or intra-interventional fluoroscopic images requires a registration process between the coordinate systems of both modalities. We present in this paper a new approach for performing this procedure by using only two external fiducial markers with integrated electromagnetic sensors which are applied on the patient's skin. Combined with the information acquired by the fluoroscopic system we achieve an automated and fast registration.
