Abstract
A system for controlling a medical device in a patient. A display system displays an image of a volume of the patient in a virtual three-dimensional space. A stylus is controllable to actuate a virtual element in the virtual space. A navigation system controls the medical device in the patient volume based on a position of the actuated virtual element. This inherently three-dimensional interface allows a physician to actuate the medical device more intuitively than possible using a two-dimensional interface.

8. A system for controlling a medical device in an operating volume in a subject, the system comprising:
-
a device localization system that determines a position of the medical device in the operating volume in the subject;
a navigation system that controls the position of the device in the operating volume in the patient based at least in part upon the position determined by teh device localization system;
a stylus controllable in a real space; and
a display system that displays the stylus as a virtual three-dimensional element relative to an image of at least part of the patient volume and communicates a position of the virtual element to the navigation system;
wherein the navigation system uses the virtual element position as an input to control the navigation system to control the medical device.
