SYTEMS AND METHODS FOR IMPROVED ELECTROMAGNETIC TRACKING

Tracking a pose of a portion of an anatomical structure using an inverted-direction electromagnetic navigation system may comprise generating a signal comprising a plurality of frequencies. The signal comprising the plurality of frequencies may be received at a transmitter coil array. The transmitter coil array comprises a plurality of transmitting micro coils. Each of the plurality of transmitting micro coils is coupled to a portion of an anatomical structure of a patient. In response to receiving the signal comprising the plurality of frequencies, an electromagnetic field may be generated at each of the plurality of transmitting micro coils based on the received signal. Each of the generated electromagnetic fields may be detected at a receiver coil array comprising at least one receiving coil. A pose of at least one of the plurality of transmitting micro coils may then be determined.
