ABSTRACT:
An electro-magnetic tracking system includes a system controller having a sensor interface, a generator, and a positioning and angular orientation configuration. The generator is responsive to the system controller for generating an electro-magnetic field that includes a tracking volume of highest accuracy. The highest accuracy corresponds to an accuracy of the sensor interface and system controller to detect a sensor physically located within the tracking volume versus a lesser accuracy of the sensor interface and system controller to detect the sensor if the sensor is located outside of the tracking volume. The positioning and angular orientation configuration is coupled to the field generator for visibly optimizing (i) a positioning and/or (ii) an angular orientation of the electro-magnetic field generator such that the tracking volume lies within a centroid of a physical volume of interest, thereby enabling a detection of a sensor within the tracking volume with a highest accuracy.
