Mixed Reality in the Operating Room

Mixed reality 3D anatomy visualization

Surgeons think in three dimensions, but most surgical imaging is shown on a flat screen. Mixed reality closes that gap. Patient-specific anatomy is rendered as interactive 3D holograms that the surgeon can review before surgery and bring into the room during the case.

Stepping inside the plan

With a system such as the Brainlab Mixed Reality Viewer, the team can rotate and explore the patient's own anatomy, understand the spatial relationships that matter, and rehearse an approach before the first incision. In complex cranial and spine work, that spatial understanding can be the difference between a confident plan and a tentative one.

Mixed reality builds on the same 3D patient model created during planning.

Connected to navigation

Mixed reality is not a standalone gadget. It draws on the same plan that drives navigation, and it can be viewed through the navigation platform in theatre, so the 3D view and the live guidance tell a consistent story.

The mixed reality view and live navigation share one plan, so the team sees a consistent picture.

Brainz sees mixed reality as a visualization layer on top of a navigated workflow, most valuable where orientation is hardest and the anatomy is most complex.
