1. A method comprising:
performing an intraoperative registration of a flexible tubular instrument to a preoperative model of a patient's anatomy, wherein the instrument includes a sensor that produces sensor data depending on a location of the sensor within the patient's anatomy, and wherein the registration is based at least in part on the sensor data;
presenting a virtual navigational image for the instrument on a display system based at least in part on the sensor data as the instrument traverses the patient's anatomy, wherein the virtual navigational image indicates a location of an anatomical target relative to a distal end of the instrument;
receiving intraoperative external image data for a portion of the patient's anatomy selected to include a region around the distal end of the instrument;
performing a tomographic reconstruction based at least in part on the intraoperative external image data; and
presenting an updated virtual navigational image for the instrument on the display system based at least in part on the tomographic reconstruction and the sensor data while the instrument is within the patient's anatomy, wherein the updated virtual navigational image includes an updated location of the anatomical target relative to the distal end of the instrument.
