An system and method for displaying a position of a medical device disposed within a region of interest in a body are provided. The system includes a position sensing system disposed outside of the body and configured to interact with a position sensor on the medical device upon generation of an electric and/or magnetic field. The sensor generates a position signal indicative of the position of the device within a coordinate system. The system further includes an electronic control unit comprising a registration module for registering a volumetric data set within the coordinate system. The unit further comprises a generation module for generating a volumetric rendering of the region of interest from the volumetric data set and a superimposition module for superimposing a representation of the medical device on the volumetric rendering responsive to the position signal.
