Estimating the term…
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.
An image-guided method comprising directing an endoscope including a tip sensor to an anatomical position in a patient;
The image-guided method of any preceding claim wherein the tip sensor is an angled coil sensor, the coil being disposed at a 45° angle relative to a core portion of the tip sensor.
The image-guided method of any preceding claim wherein orientation and location determination comprise applying a deformation vector field.
The image-guided method of any preceding claim wherein the one or more patient images are derived from an imaging device in conjunction with a patient tracking device disposed at an external region of the patient.
A method of using a guidewire or other navigated instrument with one to one rotation to continuously align a virtual display view to be consistent with an actual bronchoscopic video view.
A method of using a video input of the bronchoscope to adjust the virtual fly-through view to be consistent with a user's normal perspective.
A method of using bronchoscopic video to provide angular information at a current location to provide targeting or directional cues to the user.
