Abstract: Methods and devices are provided for determining anatomical distance and/or position measurements during an endoscopic procedure. Markings are placed either physically or superimposed on a distal end of an elongate tool, such that the markings are viewable in an imaging field of view of the endoscope. Anatomic distances may be determined by measurements performed with the tool. The size and/or position of anatomical structures or unknown objects may also be determined using the marked tool.
