Endoscopic Navigation Prototype MIT Artificial Intelligence Lab and Brigham and Women's Hospital Overview Virtual endoscopy is the navigation of a virtual camera through a 3D reconstruction of a patient's anatomy enabling the exploration of the internal structures to assist in surgical planning. Augmented endoscopy includes the registration of the patient and tracking of the endoscope to produce a visualization illustrating the position of the endoscope in the MR scan during a procedure. Prototype An augmented endoscopy guided intubation was performed on a 55 year old male with a retropharyngeal tumor using our navigation system. The patient was registered to the MR scan and tracked. A flexible endoscope and a miniature (1.2 mm diameter) electromagnetic sensor were introduced into the endotracheal tube together. During the intubation, a registered visualization of the endoscope's position was displayed in real-time. The image below illustrates an example of the display during the procedure. As the endotracheal tube progressed down the wind-pipe, the virtual endoscopic view (upper left), the 3D exterior view (upper right) and the 2D orthogonal views (bottom) updated the position of the endoscope tip.
