Abstract: Systems and methods for navigation are presented. First and second response signals received from at least one magnetic sensor operatively coupled to a target device in response to a magnetic field are measured at reference and reversed sensitivity while an alignment of magnetic domains corresponding to the magnetic sensor remains unchanged. A useful portion of the first response signal is determined by eliminating common-mode noise from the first response signal based on a difference between the first and second response signals. Alternatively, a bias signal having a desired bias frequency is applied to shift a signal frequency of a response signal of a magnetoresistance sensor that includes common-mode noise. A useful portion of the response signal is determined by measuring the response signal at a shifted frequency that is a sum of the signal and bias frequencies. A position of the subject is then determined based on the useful portion.

Abstract: A method and system for magnetically tracking a device of interest generating a plurality of pre-determined multi-frequency signals. The method and system transmits a plurality of magnetic fields from a transmitter circuit based on the corresponding pre-determined multi-frequency signals. The magnetic fields propagating through an area of examination encompassing the device of interest and a magnetic sensor coupled to the device of interest. The method and system generate a sensor signal at the magnetic sensor indicative of field strength of the magnetic fields transmitted by the transmitter circuit. Further, the method and system determine a position of the magnetic sensor relative to the transmitter circuit based on the multi-frequency signals and the sensor signal.

Abstract: Methods and systems for processing a set of images are described. In accordance with this disclosure, images are registered and an analysis is performed in view of one or more constraints (such as constraints based upon anatomical or physiological considerations). Weighting factors are determined based on the analysis. The weighting factors are used in subsequent processing of the registered (and/or unregistered) images and/or to formulate a visualization that conveys the degree of confidence in the motion estimation used in the registration process.
