A visual guidance system for use in a surgical procedure include a calibration operation of a tip of a surgical drill. In particular, the system includes capturing images of a drill tip and generating a reconstruction volume shape of the drill tip to enable tracking of the drill tip. The system captures images of the drill tip in tilting motion to determine cutting edge contour data of the drill tip. The system further captures images of the drill tip in rotation and identifies point cloud data of the drill tip. The system further includes generating a three-dimensional surface data of the drill tip, a cutting plane, and a cutting edge contour of the drill tip. Given the three dimensional surface data and plane data, the system further generates guidance data for providing a navigation on surgical procedure using three-dimensional graphical representation of the surgical drill.

The registration operation comprises a landmark point identification procedure and a landmark matching procedure. In particular, the present case is directed to automatically identifying three or more landmark points in an anatomy image by using a model according to shapes of a bone ridge depicted in the anatomy image. A graphical user interface enables interactively confirming locations of the three or more landmark points in the anatomy image. Given the identified three or more landmark points, the present case further describes interactively matching respective locations of the respective landmark points in the anatomy image with physical locations of a probe tip in anatomy according to deviation information of the probe tip. The automated identification and the interactive matching of landmark points enable generating navigational surgical guidance information with accuracy.

A visual guidance system for use in a surgical procedure. The system includes an image processing unit programmed to receive a three-dimensional image of a surgical area, information on an instrument being used in the procedure, and a surgical plan including a planned trajectory that the instrument should follow. The image processing unit generates a derived representation of the surgical procedure depicting the movement of the instrument on the three-dimensional image. A graphical guidance indicator is disposed on the three-dimensional image with a center point of the graphical guidance indicator centered on the planned trajectory, the graphical guidance indicator being displayed orthogonal to the planned trajectory. The derived image and the graphical guidance indicator depict at least five degrees of freedom of motion of the instrument. The graphical guidance indicator is changed based on the movement of the instrument in accordance with the surgical plan.
