Abstract
Tracking a pose of a portion of an anatomical structure using a bi-directional electromagnetic navigation system may include generating a signal comprising a plurality of frequencies. The signal may be received at a bi-directional coil array that comprises a plurality of bi-directional micro coils configured to both generate electromagnetic fields and detect electromagnetic fields generated by neighboring bi-directional micro coils. Each of the plurality of bi-directional micro coils may be coupled to a portion of a structure. In response to receiving the signal, an electromagnetic field may be generated at each of the plurality of bi-directional micro coils. At least one of the generated electromagnetic fields may be detected at a neighboring bi-directional micro coil of a bi-directional micro coil that is generating the at least one detected electromagnetic field. A pose of the bi-directional micro coil that is generating the at least one detected electromagnetic field may be determined.
