摘要： 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.

摘要： Disclosed is a system to track a member in a volume. The system comprises a transmitter operable to generate an electro-magnetic field at a plurality of frequencies; a tracking device having at least a first sensor configured to sense the field at each frequency of the plurality of frequencies; a transmission system to transmit a signal regarding the sensed field at each of the frequencies; a processor system configured to: receive the signal, evaluate the received signal to determine if an interference is present, if an interference is determined to be present (i) evaluate a model of a flux including two or more circuits, (ii) determine a distortion free flux based on the modeled flux extrapolated to zero frequency and (iii) output the determined distortion free flux, and determine a position of the tracking device based on a distortion free field determined based on the determined distortion free flux. The system may be used to perform a procedure on a subject. The procedure may be any appropriate procedure. The navigation system may be used to account for the distortive effects of various conductive objects positioned near the subject on which the procedure is performed.

摘要： An electromagnetic device includes a jig (170) and multiple wires. The jig includes a center member (208) and coil-separating blocks (210). The coil-separating blocks (210) protrude from the center member (208) and are separated from each other to provide coil channels (202, 204, 206). Each of the wires is wrapped on the jig (170), around the center member (208), and in one of the coil channels to form one of a multiple coils. Each of the coils is configured to connect to an electromagnetic navigation system (20) and generate respective electromagnetic fields to be emitted relative to a subject.

摘要： 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.
