Microsoft HoloLens provides the ability to visualize 3D holograms of preoperative MRI in addition to the physical environment. In this work we have developed a HoloLens application that aligns these preoperative holograms to the patient. The accuracy of perceiving these holograms was evaluated by presenting different shapes of holograms in random locations and comparing their positions to ground truth. The current set-up enables visualization and perception of holograms with a margin tolerance of < 6 mm.
