Patent ID: 8532741

Claim:
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.
