The present disclosure describes methods and systems of generating a functional flow map of a bodily structure. Methods may involve providing an intraluminal device configured for insertion into a bodily structure that is within a tracked field. The intraluminal device may include a sensor configured to obtain one or more functional flow measurements and configured to receive a signal or cause a disturbance in the tracked field. The received signal or disturbance of the sensor may be used to track one or more positions of the intraluminal device within the bodily structure. The sensor may also be used to obtain the functional flow measurements at the tracked positions. Based on the tracked positions and functional flow measurements, the functional flow map of the bodily structure may be generated.
