Abstract
Tracking a pose of a portion of an anatomical structure using an electromagnetic navigation system may comprise generating a signal. The generated signal is configured to cause bi-directional micro coils of a bi-directional coil array to generate an electromagnetic field at each bi-directional micro coil in response to receiving the generated signal. Each of the bi-directional micro coils is also coupled to a portion of a tracked structure. At least one of the generated electromagnetic fields is configured to be detected by at least one neighboring bi-directional micro coil and at least one receiving coil of a receiving coil array. A pose of a particular bi-directional micro coil of the bi-directional micro coils associated with the at least one generated magnetic field is determined based on detecting the at least one generated magnetic field at the at least one neighboring bi-directional micro coil and the at least one receiving coil.
