An imaging system for use in a medical intervention procedure is disclosed. A first image acquisition system is configured to produce a fluoroscopy image of an anatomical region. A second image acquisition system is configured to produce a 3D model of the anatomical region. An interventional tracking system, which includes a position indicator, is configured to maneuver within the anatomical region. A first anatomical reference system is common to both the first and the second image acquisition systems, and a second anatomical reference system is common to both the first image acquisition system and the interventional tracking system. 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 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.
