  • Tool calibrator and tracker system
    Patent number: 7043961
    Abstract: A standard medical or surgical tool's axis is located by attaching to the tool a plurality of a location indicating elements or markers having a known geometric or spatial relationship, and placing the tool in a tool calibrator that supports the tool in a manner that allows tools of different diameters to be rotated while maintaining the tool's axis in a fixed or stable orientation. As the tool is rotated, a marker locating system tracks the positions of the markers on the tool and then extrapolates or determines the axis of rotation with respect to the markers clamped to the tool. The tool calibrator has a second set of position indicating elements or markers with fixed geometric or spatial relationship with one another and with respect to a stop, against which the end or tip of the tool is placed.

  • Method and apparatus for surgical navigation
    Publication number: 20060084867
    Abstract: A surgical navigation system for tracking a procedure relative to a patient is disclosed. The system can track a portion of the patient, an instrument, both, and both or either relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a minimally or non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits.
