SYSTEMS AND METHODS FOR ENDOSCOPIC NAVIGATION AND BOOKMARKING

Systems and methods for determining a position of an endoscope in a portion of a body are described. In an embodiment, the system includes an endoscope comprising an endoscope body shaped to enter a portion of a body, the endoscope body defining a proximal end and a distal end opposite the proximal end; an insertion depth sensor configured to generate an insertion depth signal based on an insertion depth of the endoscope body within the portion of the body; and an inertial measurement unit disposed at the distal end of the endoscope body, the inertial measurement unit configured to generate an orientation signal based upon an orientation of the inertial measurement unit. In an embodiment, the system is configured to generate positional information of the distal end of the endoscope body within the portion of the body based upon the insertion depth signal and the orientation signal.
