Abstract

The present invention provides systems and methods for locating an imaging device within or outside of the body and for displaying a graphical representation of the imaging pattern associated with the imaging device within a global representation of the body. The imaging pattern characterizes the “field of vision” of the imaging device, and the graphical imaging pattern within the global representation of the body visually indicates the portion of the body that is being imaged by the imaging device in relation to the global representation of the body.
