Method and apparatus for virtual endoscopy
First Claim
1. A navigation system to track a surgical instrument relative to a patient, comprising:
- 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 electromagnetic 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.

21. A surgical instrument navigation system to display a virtual image from the point of view of a surgical instrument within a patient, comprising:
-
a tracking subsystem operable to capture position data indicative of the position of the surgical instrument;
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 an image of the internal region of interest from the scan image data and to superimpose an indicia of the surgical instrument onto the rendered 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 rendered image of the patient. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of creating image data representative of a point of view of a surgical instrument relative to a patient for display on a display, comprising:
-
obtaining image data of a patient;
tracking the surgical instrument;
determining a position of the surgical instrument;
determining an orientation of the surgical instrument;
creating image data relating to a point of view of the surgical instrument within the patient; and
displaying the created image data illustrating the point of view of the surgical instrument within the patient. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
