Abstract: A method comprises receiving a position of a tip portion of an instrument at a first location within a patient anatomy and determining a three-dimensional distance between the first location and a target location within the patient anatomy. The method further comprises displaying on a display system an image that includes a target location symbol and an instrument tip portion symbol. The method further comprises displaying on the display system a symbol indicating a direction between the position of the tip portion and the target location. As the tip portion of the instrument changes position, the image is displayed so that the instrument tip portion symbol is a frame of reference for the image and the target location symbol moves with respect to the instrument tip portion symbol to represent a new location of the tip portion relative to the target location.
