    摘要： A system and method are provided for obtaining registration of a localization system's three-dimensional coordinates for a plurality of markers having known locations to the two-dimensional coordinates for the plurality of reference markers obtained from a single X-ray image. The method for registering a navigational system with a localization system having a plurality of reference markers includes determining the three-dimensional coordinates of the locations of a plurality of reference markers within the localization coordinate system, and providing a single two-dimensional X-ray image that includes a two dimensional location of the plurality of markers. The method further includes determining a coordinate transformation for obtaining a best fit registration of the localization system's three-dimensional coordinates to the two-dimensional coordinates obtained from the single X-ray image, for at least one reference marker location.

    摘要： A method of navigating a medical device includes determining the location of a medical device at a point in an operating region in a subject's body, the medical device being responsive to at least one control variable to assume a desired configuration includes storing information representative of the at least one control variable being applied to the medical device at the point, and more preferably storing information representative of the at least one control variable and the device length.
