摘要:
A location of a number of fiducial points can be computed. The fiducial points can include impedance locations of an electrode disposed on a catheter in an impedance based coordinate system and magnetic locations of a magnetic position sensor disposed on the catheter in a magnetic based coordinate system. The impedance location of the electrode in the impedance based coordinate system can be transformed into a transformed impedance location of the electrode in the magnetic based coordinate system. A magnetic location of the electrode in the magnetic based coordinate system can be determined. A determination of whether an impedance shift exists between the transformed impedance location of the electrode in the magnetic based system and the magnetic location of the electrode in the magnetic based system can be made. An electromagnetic dynamic registration can be generated between the impedance based coordinate system and the magnetic based coordinate system based on the impedance shift.
