Abstract
In one aspect of the present technique, an array of electromagnetic sensors is positioned within a volume of interest. In the presence of an electromagnetic field, the array of electromagnetic sensors is sampled to acquire signals representative of the location of the electromagnetic sensors in the array. The electromagnetic field distortion within the volume of interest is determined based on the acquired signals. In another aspect of the present technique, a system for detecting electromagnetic field distortions includes an electromagnetic sensor assembly for positioning within a volume of interest, a plurality of electromagnetic sensors for transmitting or receiving signals representative of the location of the electromagnetic sensors on the sensor assembly; and a tracker. In another aspect of the present technique, an electromagnetic sensor assembly for detecting electromagnetic field distortion includes a body, and an array of electromagnetic sensors positioned on the body.
