Abstract: Certain embodiments of the present invention provide a method for correlating data including: receiving from a tracking subsystem a first data set including a tracked position of an object; receiving from an imaging subsystem a second data set including an image of the object; and comparing automatically at least a portion of the first data set with at least a portion of the second data based at least in part on the tracked position of the object and the image of the object. In an embodiment, the comparing automatically the first data set with the second data set is performable in real-time. In an embodiment, the method further includes registering the first data set with the second data set. In an embodiment, the tracking subsystem tracks the object electromagnetically, at least in part. In an embodiment, the imaging subsystem includes an x-ray imaging subsystem. In an embodiment, the first data set is generatable by the tracking subsystem substantially in real-time.

Abstract: A method for electromagnetic tracking the position and orientation of an object using a discretized numerical field model, rather than the conventional analytical dipole model. The method including the steps of determining a discretized numerical field model associated with a particular distortion source; acquiring mutual inductance signals between electromagnetic sensors and the particular distortion source, the sensors being rigidly attached to a tracked object; estimating an initial position for the tracked object in the presence of the particular distortion source; refining the estimated position of the tracked object; and estimating an orientation of the tracked object.

Abstract: A system and method of minimizing the mutual inductance coupling between two or more coils of a coil array of an electromagnetic tracking system. The system involves a geometric arrangement of two or more coils, which significantly reduces any mutual inductance coupling between the two or more coils. The method involves characterization of two or more coils and compensating for mutual inductance coupling between the characterized two or more coils.
