1. A local positioning system (LPS) comprising:
at least three local position tracking devices, each local position tracking device further comprising:
a clock synchronized to the clock in each of the other local position tracking devices;
a transmitter transmitting messages over time synchronized to the clock, each of the messages comprising a time that the message was transmitted and known initial positional information of the transmitting local position tracking device with respect to each of the other local position tracking devices; and
a receiver receiving the messages over time from the other local position tracking devices;
an image visualization representation of a living body as represented over time and comprising a plurality of time-sequential frames corresponding with the locations of each of the at least three local position tracking devices over time;
a processor operatively coupled as part of at least one of the at least three local position tracking devices, wherein
the processor is configured to create and generate a temporally-changing coordinate map over time based on, for each of the messages, the time that the message was transmitted, a time that the message was received and the known initial positional information,
the processor is further configured to combine the plurality of the time-sequential frames of the image visualization representation at the same time as the creation and generation of the temporally-changing coordinate map into a plurality of enhanced frames, and
the processor is still further configured to continually output the enhanced frames to a computer system.
