Claim Text:
1. A method, comprising: tracking a location of a target using a first imaging device, wherein the target is an anatomical structure in a body and the first imaging device is external to the body; determining that the target is not in an imaging field of the first imaging device or is near a boundary of the imaging field; automatically adjusting a location of the first imaging device to cause the target to be in the imaging field responsive to determining that the target is not in the imaging field or is near the boundary of the imaging field; tracking the location of the first imaging device using a second imaging device, wherein the first imaging device is in a tracking field of the second imaging device while the location of the target is tracked using the first imaging device and while the location of the first imaging device is tracked using the second imaging device; and determining the location of the target relative to a global reference point based on the location of the target from the first imaging device, the location of the first imaging device from the second imaging device, and a location of the second imaging device, wherein determining the location of the target relative to the global reference point comprises determining a first positional offset between the target and the first imaging device, determining a second positional offset between the first imaging device and the second imaging device, determining a third positional offset between the second imaging device and the global reference point, and combining the first positional offset, the second positional offset and the third positional offset.
