MAGNETIC TRACKER SYSTEM AND METHOD FOR USE FOR SURGICAL NAVIGATION |
摘要 |
A method and system for magnetically tracking a device of interest generating a plurality of pre-determined multi-frequency signals. The method and system transmits a plurality of magnetic fields from a transmitter circuit based on the corresponding pre-determined multi-frequency signals. The magnetic fields propagating through an area of examination encompassing the device of interest and a magnetic sensor coupled to the device of interest. The method and system generate a sensor signal at the magnetic sensor indicative of field strength of the magnetic fields transmitted by the transmitter circuit. Further, the method and system determine a position of the magnetic sensor relative to the transmitter circuit based on the multi-frequency signals and the sensor signal. |

1. A method for magnetically tracking a device of interest, the method comprises:
generating a plurality of pre-determined multi-frequency signals; transmitting a plurality of magnetic fields from a transmitter circuit based on the corresponding pre-determined multi-frequency signals, the magnetic fields propagating through an area of examination encompassing a device of interest and a magnetic sensor coupled to the device of interest; generating a sensor signal at the magnetic sensor indicative of field strength of the magnetic fields transmitted by the transmitter circuit; and determining a position of the magnetic sensor relative to the transmitter circuit based on the multi-frequency signals and the sensor signal. |
