Surgical navigation enabled imaging table environment
View Patent ↗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.
1. 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.
2. The surgical navigation system of claim 1 , wherein the plurality of magnetoresistance sensors are integrated within a table.
3. The surgical navigation system of claim 2 , wherein the table is radiolucent.
4. The surgical navigation system of claim 1 , wherein the plurality of magnetoresistance sensors are integrated within a table mat positioned adjacent to the surface of the table.
5. The surgical navigation system of claim 4 , wherein the table mat is radiolucent.
6. The surgical navigation system of claim 1 , wherein the plurality of magnetoresistance sensors are integrated within a surgical drape positioned over a patient.
7. The surgical navigation system of claim 6 , wherein the surgical drape is radiolucent.
8. The medical table of claim 1 , wherein each of the plurality of the magnetoresistance sensors have an active area of 0.1 mm by 0.1 mm.
9. 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;
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.
10. The surgical navigation system of claim 9 , wherein the plurality of magnetoresistance sensors are integrated within a table mat positioned adjacent to the surface of the table.
11. The surgical navigation system of claim 10 , wherein the table mat is radiolucent.
12. The surgical navigation system of claim 9 , wherein the plurality of magnetoresistance sensors are integrated within a surgical drape positioned over a patient.
13. The surgical navigation system of claim 12 , wherein the surgical drape is radiolucent.
14. The surgical navigation system of claim 9 , wherein the table is radiolucent.
15. A medical table with embedded tracking technology for use in a surgical navigation system, the medical table comprising:
a plurality of magnetoresistance sensors integrated within the medical table;
wherein each of the plurality of magnetoresistance sensors 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.
