Abstract
A system for integrating radiolucent tracking sensors in a medical table, table mat, or surgical drape of a surgical navigation system, allowing the surgical navigation system to be less obtrusive in a surgery environment. A plurality of radiolucent magnetoresistance sensors are integrated into a table, table mat, or surgical draping of a surgical navigation system for improving surgical navigation workflow and eliminating image artifacts from intraoperative images. The plurality of radiolucent magnetoresistance sensors may be located within a table or adjacent to a table surface.
Claims15
A surgical navigation system comprising:
- at least one magnetoresistance sensor attachable to at least one device;
- a plurality of magnetoresistance sensors integrated within a table or adjacent to a surface of the table;
- and
- at least one processor for determining the position and orientation of the at least one device;
- wherein the at least one magnetoresistance sensor attachable to the at least one device and the plurality of magnetoresistance sensors integrated within the table each comprising:
- an insulating substrate;
- an alternating pattern of a metal material and a semiconductor material deposited on a surface of the insulating substrate;
- and
- a bias magnet material deposited on a surface of the alternating pattern of the metal material and the semiconductor material;
- and
- wherein the alternating pattern of the metal material and the semiconductor material is between the insulating substrate and the bias magnet material.
A surgical navigation system comprising:
- at least one magnetoresistance sensor attachable to at least one device;
- a magnetoresistance reference sensor rigidly attachable to an anatomical reference of a patient;
- a plurality of magnetoresistance sensors integrated within a table or located adjacent to a surface of the table;
- and
- at least one processor for determining the position and orientation of the at least one device;
- wherein the at least one magnetoresistance sensor attachable to the at least one device and the plurality of magnetoresistance sensors integrated within the surgical navigation table each comprising:
- an insulating substrate;
