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.
