The Pilot Tone navigator is a novel electromagnetic motion sensing method capable of contactless respiratory and cardiac motion sensing. We demonstrate the physical processes underlying the Pilot Tone navigator using electromagnetic simulations on a realistic virtual human phantom and validate these simulation results in-vivo. These simulations can be used to investigate how the PT signal is shaped by motion of the underlying anatomy with the aim of using this information to aid in improving our processing pipeline.
