A local positioning system (LPS) that includes at least three local position tracking devices is described. Each local position tracking (LPT) device includes a device clock synchronized to a device time set and shared by the other device clocks, a transmitter transmitting messages synchronized to the device time, each message including a transmission time and known initial positional information, and a receiver. A living body image visualization includes time-sequential frames corresponding with the other LPT device. An output component includes a user clock set to a user time. A processor includes a processor clock set to a processor time. The processor generates a temporally-changing coordinate map based on transmission time, receipt time and the known initial positional information. The processor combines the time-sequential frames at the same time as the temporally-changing coordinate map into enhanced frames continually output. The device time, the user time, and the processor time are synchronized.
