Method and apparatus for virtual endoscopy
First Claim
1. A surgical instrument navigation system, comprising:
- a surgical instrument;
a tracking subsystem operable to capture in real-time position data indicative of the position of the surgical instrument;
a data processor adapted to receive scan data representative of a region of interest of a given patient and the position data from the tracking subsystem, the data processor being operable to render an image of the region of interest from a point of view which relates to position of the surgical instrument, the image being derived from the scan data; and
a display in data communication with the data processor, the display being operable to display the image of the patient.

Abstract
A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

12. A surgical instrument navigation system, comprising:
-
a surgical instrument;
a timing signal generator operable to generate and transmit a timing signal that correlates to at least one anatomical function of the patient;
a tracking subsystem operable to receive the timing signal from the timing signal generator, the tracking subsystem operable to capture position data indicative of the position of the surgical instrument and to report the position data in response to the timing signal received from the timing signal generator;
a data processor adapted to receive scan image data representative of an internal region of interest within a given patient and the position data from the tracking subsystem, the data processor being operable to render a volumetric perspective image of the internal region of interest from the scan image data and to superimpose an indicia of the surgical instrument onto the volumetric perspective image based on the position data received from the tracking subsystem; and
a display in data communication with the data processor, the display being operable to display the volumetric perspective image of the patient. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A surgical instrument navigation system, comprising:
-
a surgical instrument;
an imaging device operable to capture volumetric scan data over time, the volumetric scan data representative of an internal region of interest within a patient and the internal region of interest having motion that is caused by at least one anatomical function of the patient;
a timing signal generator operable to generate and transmit a timing signal that correlates to the at least one anatomical function of the patient;
a data processor adapted to receive the volumetric image data from the imaging device and the timing signal from the timing signal generator, the data processor being operable to render a volumetric perspective image from the viewpoint of the surgical instrument of the internal region of interest over time, the volumetric perspective image being derived from the volumetric scan data and synchronized with the timing signal; and
a display in data communication with the data processor, the display being operable to display the volumetric perspective image of the patient. - View Dependent Claims (24, 25)

26. A surgical instrument navigation system, comprising:
-
a non-imaging surgical instrument;
a tracking subsystem operable to capture in real-time position data indicative of the position of the non-imaging surgical instrument;
a data processor adapted to receive scan data representative of a region of interest of a given patient and the position data from the tracking subsystem, the data processor being operable to render an image of the region of interest from a point of view which relates to the position of the surgical instrument; and
a display in data communication with the data processor, the display being operable to display the image of the patient;
wherein the rendered image being derived from the scan data.
