Abstract: A method for detecting EM field distorting includes sampling a sensor assembly positioned within a volume of interest to acquire measurements of EM fields within the volume of interest, and monitoring the measurements to detect EM field distortion within the volume of interest. The sensor assembly includes a set of EM transmitters and a set of EM receivers fixed thereon. A system for detecting EM field distorting includes a sensor assembly for positioning within a volume of interest, wherein the EM sensor assembly comprises a set of EM receivers, and a set of EM transmitters, wherein the EM receivers and the EM transmitters are disposed at fixed locations on the sensor assembly. The system further includes a tracker configured to sample the sensor assembly to acquire measurements of EM fields generated by the EM transmitters, and monitor the measurements to detect EM field distortion within the volume of interest.

Abstract: Systems and methods for tracking a surgical instrument and for conveying tracking information via a network provide a primary tracking image generally within an operating room, and also a variety of types of secondary tracking images, either outside of the operating room or within the operating room.
