REAL-TIME SCOPE TRACKING AND BRANCH LABELING WITHOUT ELECTRO-MAGNETIC TRACKING AND PRE-OPERATIVE SCAN ROADMAPS

摘要

A system and method for locating a position of an imaging device include a guided imaging device (102) configured to return images of internal passageways to a display (124). A processing module (114) is configured to recognize patterns from the images and employ image changes to determine motion undergone by the imaging device such that a position of the imaging device is determined solely from information received from images obtained internally in the passageways and general knowledge of the passageways.
