A registration method whereby a sensor-based approach is used to establish initial registration and whereby upon the commencement of navigating an endoscope, image-based registration methods are used in order to more accurately maintain the registration between the endoscope location and previously-acquired images. A six-degree-of-freedom location sensor is placed on the probe in order to reduce the number of previously-acquired images that must be compared to a real-time image obtained from the endoscope.
1. A method of registering real-time sensor location data to previously acquired images of a branched network of body lumens comprising: placing a probe containing a sensor at a distal end thereof in branched network of body lumens in a patient;placing a plurality of patient sensors on said patient;
1. A method of registering real-time sensor location data to previously acquired images of a branched network of body lumens comprising: placing a probe containing a sensor at a distal end thereof in branched network of body lumens in a patient;placing a plurality of patient sensors on said patient;recording an image of an anatomical landmark in said patient as said landmark moves through at least one breathing cycle;recording concurrently a position of said sensor;recording concurrently positions of patient sensors, said patient sensor attached at various locations on said patient;saving said recordings as a data set for said landmark; and,using said data set to correlate said position of said sensor to a previously acquired image of said branched network of body lumens. 2. The method of claim 1 wherein placing a plurality of patient sensors on said patient comprises affixing said plurality of patient sensors to said patient's chest. 3. The method of claim 1 wherein placing a plurality of patient sensors on said patient comprises affixing a plurality of patient sensors to said branched network. 4. The method of claim 1 wherein using said data set to correlate said position of said sensor to a previously acquired image of said branched network of body lumens comprises using said data set to correlate said position of said sensor to a previously acquired CT image of said branched network of body lumens.
