Method and system for concurrent localization and display of a surgical catheter and local electrophysiological potential curves

An x-ray recording system, comprising:

• a surgical catheter configured to acquire data for electrophysiological potential curves at a plurality of positions in a vessel or organ;
• an x-ray system configured to record an x-ray image at each position;
• a registration system connected to the x-ray system configured to record the electrophysiological potential curves;
• an activating unit configured to activate at least one of the recorded x-ray images or at least one of the recorded electrophysiological potential curves, and
• a screen, wherein the at least one activated recorded x-ray image or the at least one activated recorded electrophysiological potential curve is displayed on the screen,
• wherein the registration system is configured to interrelate the electrophysiological potential curves to the x-ray images such that upon activating the at least one recorded x-ray image's respective electrophysiological potential curve the interrelated electrophysiological potential curve respectively x-ray image is queried;
• wherein querying the interrelated electrophysiological potential curve respectively x-ray image includes displaying the interrelated electrophysiological potential curve respectively x-ray image on the screen,
• wherein different electrophysiological potential curves are displayed in different colors, and a related marker is displayed in such color corresponding to the respective electrophysiological potential curve, and
• wherein the different colors are determined by a color coding algorithm, the color coding algorithm based on a delay time of a signal included in the electrophysiological potential curves, the delay time of the signal calculated relative to a reference signal provided by the reference catheter.
