DEVICE AND METHOD FOR NAVIGATING A CATHETER |
摘要 |
The invention relates to a device and a method for navigating a catheter in the vessel system or an intervention needle in an organ of a patient that is subject to a spontaneous movement due to heartbeat and/or respiration. In this connection, a movement model ( 11 ) that describes the displacement of points in the vessel system with respect to a reference phase (E<SUB>0</SUB>) of the spontaneous movement is kept ready in the memory of a data processing device ( 10 ). The spatial positions and orientations of the instrument ( 4 ) measured by a locating device ( 2 ) in the vessel system of the patient ( 3 ) and also the ECG values (E) recorded in parallel therewith are converted by the data processing device ( 10 ) with the aid of the movement model ( 11 ) into a movement-compensated position (r+Delta) of the instrument that can then be displayed in a static vessel or organ map ( 12 ). The movement model ( 11 ) can be obtained from a series of three-dimensional recordings of the vessel system. In addition or alternatively, measured positions and orientations of the instrument ( 4 ) can be used during times at which the instrument does not travel forwards. |
