Simple 2-D trajectory planning enhances usability in 3D by enabling you to set your trajectory on a 2D slice. This involves selecting your target and entry point. By setting trajectories in 2D, you can enjoy a more precise and accurate planning feature, as well as easier accessibility.
When used for patient positioning, setting a trajectory helps with the ability to visualize and plan a surgical route. Once the trajectory is set and the Hololens 2 is connected, the planned trajectory can be viewed in a 3D rendering. This assists in avoiding certain anatomical structures during the approach.
