Methods, systems, and apparatuses for visualizing the motion box of an electromagnetic sensor tracking system on a display that can be viewed by the physician are disclosed. Electromagnetic sensor tracking systems are able to determine the position and orientation (P&O) of the sensors being tracked only when the sensors are within the motion box, or the spatial region located in proximity to the electromagnetic field generators of the system. During usage of the electromagnetic sensor tracking system, the sensor can go out of this spatial region and, when this occurs, navigating it back into the motion box can be difficult. The methods, systems, and apparatuses described herein provide for the representation of sensors, the motion box, and a representation of a thorax on a display so that the clinician can view the position and orientation of the sensors with respect to the motion box.
