Abstract—Augmented reality (AR) technology has incorporated refined sensory perception into complex neurosurgical procedures in recent years. Practitioners used head mounted displays to access neuro-navigation in surgical preparations in pursuit of maximum safety. This paper was aimed to converge a target reference from imagery to an actual object by using Microsoft HoloLens. Reference registration is achieved through object scanning that utilizes phase detection of a sensor module to assign distinctive digital reference points. The navigation system then correlates the digital data with formulated computed tomography (CT) scans to accurately overlay holographic projections. Aside from sectioning the spine model projection, the interactive capability of the system extends through motion gesture and voice control to further emphasize on the hands-free experience in neutralizing surgical tension. Testing showed promising visual accuracy with fast processing response. This work explored the possibility of conducting neuro-navigation without reliance of an additional image guide.
