In one embodiment, an apparatus includes a medical instrument, a position tracking system to track coordinates of the instrument within a passage in a body, a processor to register the system and a 3D CT image of at least a part of the body, find a path of the instrument through the passage, compute segments of the path, compute respective locations along the path of respective virtual cameras responsively to the computed segments, select the respective virtual cameras for rendering respective virtual endoscopic images responsively to the tracked coordinates, compute respective orientations of the respective virtual cameras, and render and display the respective virtual endoscopic images, based on the 3D CT image, of the passage in the body viewed from the respective locations and orientations of the respective virtual cameras including an animated representation of the instrument positioned in the respective virtual endoscopic images in accordance with the tracked coordinates.

3D pathfinder visualization

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

Method for real time update of fly-through camera placement

Apparatus, including a patient tracker, attached to a subject, having magnetic field sensors and optical landmarks with known spatial relationships to each other. A camera acquires a 3D optical image, in a first frame of reference (FOR), of the subject's face. A magnetic radiator assembly generates magnetic fields at the subject's head, thereby defining a second FOR. A processor: processes field sensor signals to acquire location coordinates of the sensors in the second FOR; segments a tomographic image of the subject, having a third FOR, to identify the subject's face in the third FOR; computes a first transformation between the third and first FORs to map the tomographic face image to the 3D optical image; maps the optical landmarks to the third FOR; maps the respective location coordinates of the sensors to the first FOR; and computes a second transformation between the second FOR and the third FOR.

Registration of frames of reference

An endoscopic camera has two or more cameras positioned at a distal end, positioned to provide partially overlapping fields of view. The cameras communicate captured digital images the length of the flexible endoscope, where they may be saved and processed to provide additional imaging features. With partially overlapping images from two or more cameras, image processing can provide panoramic images, super resolution images, and three-dimensional images. One or more of these image modes may also be enhanced to provide a virtualization window that displays a portion of a larger or higher resolution image. The virtualization window displays the selected area of the image, and may be moved or zoomed around the image to provide a virtual endoscope repositioning experience, where the endoscope remains statically positioned but the virtualization window presents a sense of movement and navigation around the surgical area.
