Abstract
A method and apparatus can be used to guide or navigate an instrument relative to a body. Various types of information can be used to assist in the navigation, such as MRI data, diffusion tensor image data, and the like. The information can assist in identifying the portions of the body.
Claims30
A method of performing a procedure on a selected portion of an anatomy, comprising:
- accessing image data of the selected portion of the anatomy;
- accessing a second source of data relating to the selected portion of the anatomy;
- analyzing the second source of data;
- identifying a fiber tract in the accessed image data based on the analyses of the second source of data;
- determining a selected position of treatment in the anatomy based on the accessed image data and the identified fiber tract to initially and directly affect the identified fiber tract with a treatment;
- providing an output from a processor to display a target icon on a display device superimposed on the accessed image data to illustrate the selected position in the anatomy;
- determining a location of an instrument with the processor via tracking a tracking device associated with the instrument by interaction with a localizer of a tracking system;
- providing an output from the processor to display an instrument icon superimposed on the accessed image data on the display based upon the determined location;
- moving and navigating the instrument to the selected position of treatment identified by the superimposed target icon, further comprising,
- executing instructions with the processor to plan at least a portion of a planned trajectory;
- superimposing a planned trajectory icon on the accessed image data relative to the superimposed target icon on the display device illustrating the planned trajectory;
- and
- updating the display to illustrate the determined location of the instrument as the instrument icon representing the location of the instrument relative to the target icon and the planned trajectory icon;
- and
- applying a treatment to the selected position in the anatomy with the instrument to efficiently affect the fiber tract after the instrument reaches the selected position illustrated by the target icon that is superimposed on or adjacent to a portion of the accessed image data, wherein the fiber tract includes at least an axon.

A method for performing a surgical procedure on an anatomy, comprising:
- obtaining data regarding the anatomy;
- analyzing the obtained data;
- selecting an identified fiber tract in the anatomy based upon the analyzed obtained data to apply a selected therapy, wherein the selected therapy includes applying stimulation to a fiber tract within the anatomy;
- executing instructions with a processor to determine a target location relative to the selected and identified fiber tract where the selected therapy is operable to be efficiently applied to directly affect the selected and identified fiber tract;
- and
- displaying:
- a target location icon representing the determined target location on a display device;
- an instrument icon representing a navigated instrument relative to the anatomy and the selected and identified fiber tract at least by viewing the display;
- and
- wherein the selected therapy is applied with the instrument that has been navigated relative to the anatomy and the selected identified fiber tract as illustrated with the instrument icon relative to the displayed target icon to stimulate the selected identified fiber tract.

A method for performing a surgical procedure on an anatomy, comprising:
- operating a processor system, including:
- obtaining image data of a selected portion of the anatomy;
- obtaining a diffusion tensor data relating to the selected portion of the anatomy;
- analyzing the diffusion tensor data;
- identifying a fiber tracts in the obtained image data at least in part with the analyses of the diffusion tensor data;
- selecting at least one of the identified fiber tracts;
- determining a target location near the selected fiber tract so that a selected therapy is to initially affect the selected fiber tract and where the selected therapy is operable to be efficiently applied to directly affect the selected fiber tract, and
- displaying a target location icon representing the determined target location on a display device;
- navigating an instrument relative to the anatomy and the selected fiber tract at least by viewing the display for applying the selected therapy with the instrument that has been navigated relative to the anatomy and the selected fiber tract to stimulate the selected fiber tract;
- and
- applying the selected therapy by stimulating the selected fiber tract within the selected portion of the anatomy.
