In many bedside procedures, surgeons must rely on their spatiotemporal reasoning to estimate the position of an internal target by manually measuring external anatomical landmarks. One example of such a procedure is ventriculostomy, where the surgeon inserts the catheter in the patient's skull to divert the cerebrospinal fluid and alleviate the intracranial pressure. However, one-quarter to one-third of the insertions miss the target which can ultimately lead to undesirable surgical outcomes. We have developed an interactive navigation system using mixed reality on a head-mounted display that overlays the target directly on the patient's anatomy and provides visual guidance for the surgeon to insert the catheter on the correct path to the target.
