1. A method of registering sensor location data to images of at least one body lumen, comprising: placing a probe including a sensor disposed thereon relative to at least one body lumen in a patient; sensing an electromagnetic field generated by an electromagnetic field generator; generating location data corresponding to a location of the sensor in the electromagnetic field; registering the location of the sensor relative to a previously acquired image selected from a memory of a computing device storing a plurality of previously acquired images of the at least one body lumen based on the location data; generating a subgroup of the plurality of previously acquired images based on the location data; and updating the registered location of the sensor based on an image selected from the subgroup.
