  • Publication number: 20090118742
    Abstract: A system for tracking a navigated instrument. The system can include a first elongated instrument and a second elongated instrument. The first elongated instrument can have a first proximal end and a first distal end. The first elongated instrument can be adapted to be positioned relative to an anatomy. The second elongated instrument can move adjacent to the first elongated instrument. The second elongated instrument can have a second proximal end and a second distal end. The system can also include at least one tracking device coupled to the second elongated instrument. When the second elongated instrument is in a first position, the at least one tracking device tracks the first distal end of the first elongated instrument, and when the second elongated instrument is in a second position, the at least one tracking device tracks the second distal end of the second elongated instrument.

  • Publication number: 20080262338
    Abstract: A system and method is disclosed that can be used to track and navigate an instrument relative to a patient. The system can include an electromagnetic tracking system to track an electromagnetic stimulation probe, such as a transcranial magnetic stimulation probe. The system can, according to various embodiments, provide a tracking device on the probe, track the coil of the probe, provide a field relative to the probe, and determine the position of the patient based upon the field produced by the probe.

  • Publication number: 20080214922
    Abstract: The position of an imaging device can be determined at least in part with a movement portion of the imaging device. The imaging device can be moved relative to the patient to obtain image data of the patient at different perspectives or angles. The image data obtained of the patient can be displayed with a display device at various perspectives and a tracked position of the instrument can be displayed at the appropriate perspective or a selected perspective relative to the image data with the display device based upon a known position of the imaging device.

  • Publication number: 20080200794
    Abstract: A navigation system generally determines a location of a portion of a first medical instrument relative to a patient. The navigation system generally includes a multi-configuration tracking array that extends from the first medical instrument. A plurality of tracking devices can be positioned on the multi-configuration tracking array. At least one of the tracking devices changes to define at least a first condition and a second condition. A tracking system detects the tracking devices and relates a change between the first condition and the second condition with a change between at least a first instrument configuration and a second instrument configuration.
