1. An imaging system for use in a medical intervention procedure, comprising:

  • a first image acquisition system configured to produce a fluoroscopy image of an anatomical region;

    a second image acquisition system configured to produce a 3D model of the anatomical region;

    an interventional tracking system configured to maneuver within the anatomical region, the interventional tracking system comprising a position indicator, the position indicator providing signals indicating coordinates of the position indicator in the anatomical region;

    a first anatomical reference system common to both the first and the second image acquisition systems;

    a second anatomical reference system common to both the first image acquisition system and the interventional tracking system, the coordinates of the position indicator being in the second anatomical reference system; and

    a processing circuit configured to process executable instructions for;

    registering the second image acquisition system with the first image acquisition system to define a first registration;

    registering the interventional tracking system with the first image acquisition system utilizing the signals from the position indicator to define a second registration; and

    in response to the first and second registrations, registering the interventional tracking system with the second image acquisition system using both the first and second registrations.
