    摘要: Certain embodiments of the present invention provide systems and methods of improved medical device navigation. Certain embodiments include acquiring a first image of a patient anatomy, a second image of patient anatomy, and creating a registered image based on the first and second images. Certain preferred embodiments teach systems and methods of automated image registration without the use of fiducial markers, headsets, or manual registration. Thus the embodiments teach a simplified method of image registration that allows a medical device to be navigated within a patient anatomy. Furthermore, the embodiments teach navigating a medical device in a patient anatomy with reduced exposure to ionizing radiation. Additionally, the improved systems and methods of image registration provide for improved accuracy of the registered images.

    摘要: In one aspect of the present technique, a method for selecting between a plurality of electromagnetic sensors to correct for one or more field distortions includes, in the presence of an electromagnetic field, acquiring signals representative of the location of a plurality of electromagnetic sensors. The method further includes selecting between the signals from the plurality of electromagnetic sensors based on one or more quality metrics. In another aspect of the present technique, a system for selecting an optimum EM sensor to correct for one or more field distortions includes a plurality of EM sensors and an additional EM sensor for transmitting or receiving signals representative of the location of each of the plurality of EM sensors. The system further includes a controller configured to acquire signals representative of the location of the plurality of EM sensors, and select between the signals from the plurality of EM sensors based on one or more quality metrics.
