Claim Text:
1. A local positioning system (LPS) comprising: a plurality of local position tracking devices with at least two of the local position tracking devices comprising components adapted to be distributed in different locations about a living body and at least one of the local position tracking devices comprising a further component adapted to be paired with the living body, each local position tracking device further comprising a transmitter and receiver with which to continually communicate in a message a time that the message was transmitted from the local position tracking device and a distance of the local position tracking device from each of the other local position tracking devices; a master transmitter and receiver communicatively interfaceable to the local position tracking devices and configured to create a temporally-changing coordinate map and to continually revise the temporally-changing coordinate map using the positional coordinates of each local position tracking device within the temporally-changing coordinate map where the temporally-changing coordinate map is based on at least one of the times in the messages continually communicated from each of the local position tracking devices and from the local position tracking devices' distances in the messages continually communicated from each of the other local position tracking devices; an imaging display configured to continually output the temporally-changing coordinate map prior to creation and registration of any image visualization of the living body; and a barrier adapted to physically surround both the living body, the master transmitter and receiver and the plurality of local position tracking devices and defining an isolated space that is shielded from electromagnetic energy interference.
