1. A navigation system for inserting a medical instrument in a patient, the system comprising:

  • a medical instrument;

    a processing device;

    an angiogram x-ray system in communication with the processing device and capable of capturing a series of angiographic images of the patient during the insertion of the medical instrument in the patient wherein at least one of the angiographic images captures the medical instrument that was inserted into an area of the patient; and

    a position capture module configured to get position information about the position of the medical instrument from angiographic images of the progress of the medical instrument generated by the angiographic x-ray system, the position capture module in communication with the processing device;

    the processing device superimposing the position information about the medical instrument on a roadmap image, wherein the roadmap image is one of the series of angiographic images generated by the angiographic x-ray system, the processing device updating the roadmap occasionally during the insertion of the medical instrument in the patient, the processing device superimposing subsequent angiographic images on the updated roadmap.
