Abstract
A magnetic sensor navigation system is disclosed, which includes: (a) a magnetic sensor array, including one or more magnetic non-Faradaic sensors; (b) a sensor interface operatively connected to receive a signal from each sensor of the array, wherein the sensor interface operates to generate a processed signal from one or more signals received from each sensor of the array; and (c) a processing and control unit connected to receive the processed signal, wherein the processing and control unit operates to calculate a spatial position of the sensor array using the processed signal when the sensor array is placed within a magnetic resonance environment of an MR scanner.
