1. A medical system comprising:
a memory storing machine executable instructions;
a processor configured for controlling the medical system; and
a pilot tone system;
wherein the pilot tone system comprises:
a radio frequency system comprising multiple transmit channels and multiple receive channels, wherein the multiple transmit channels are configured for each transmitting unique pilot tone signals via multiple transmit coils wherein the multiple receive channels are configured for receiving multi-channel pilot tone data via multiple receive coils;
wherein execution of the machine executable instructions causes the processor to:
transmit multi-channel pilot tone signals by controlling at least a portion of the multiple transmit channels to transmit the unique pilot tone signals;
acquire multi-channel pilot tone data due to impedance response to the transmitted pilot tone signals by controlling at least a portion of the multiple receive channels to receive the multi-channel pilot tone data; and
determine a motion state of the subject using the multi-channel pilot tone data.
