There have been lots of work in Slicer for pedicle screw insertion planning and guidance (by augmented reality using HoloLens, ultrasound guidance, etc.). There is a complete open-source implementation for HoloLens/Slicer see github repository here (and related [paper](https://www.researchgate.net/publication/371537888_Real-time_integration_between_Microsoft_HoloLens_2_and_3D_Slicer_with_demonstration_in_pedicle_screw_placement_planning)): > **[GitHub - BSEL-UC3M/HoloLens2and3DSlicer-PedicleScrewPlacementPlanning: GitHub repository for the IJCARS paper: "Real-Time...](https://github.com/BSEL-UC3M/HoloLens2and3DSlicer-PedicleScrewPlacementPlanning)** > > GitHub repository for the IJCARS paper: "Real-Time open-source integration between Microsoft HoloLens 2 and 3D Slicer" No need to mess with Blender, but the scene is generated in Slicer and sent to the HoloLens directly from there in real-time. Rendering in this repository is done via Unity, but recent Slicer versions can render directly to any AR/VR headset (via OpenXR API). So, there is no need to use multiple applications and programming languages (everything can be implemented in a single Slicer application, in Python or C++). What AR headset are you planning to use now that the HoloLens is dead? Video passthrough in Meta Quest 3? --- _[View the full topic](https://discourse.slicer.org/t/creating-a-drill-trajectory/28298)._
