1. A method of aligning an untrackable medical instrument during a medical procedure, the method comprising:
employing a tracking system to detect signals from fiducial markers associated with a trackable medical instrument;
processing the signals to determine, in a frame of reference associated with the tracking system, an intraoperative orientation and position of the trackable medical instrument;
employing a camera to obtain an intraoperative video feed;
displaying the intraoperative video feed;
during a subsequent phase of the medical procedure involving the untrackable medical instrument, employing a coordinate transformation between a frame of reference associated with the camera and the frame of reference associated with the tracking system to augment the intraoperative video feed with a virtual display feature identifying the previously determined intraoperative orientation and position of the trackable medical instrument; and
employing the virtual display feature within the augmented intraoperative video feed to align the untrackable medical instrument relative to the previously determined intraoperative orientation and position of the trackable medical instrument;
wherein the untrackable medical instrument is untrackable by the tracking system.
