Augmented Reality Neurosurgical Navigation

Neurosurgery with VisAR

Like a surgical GPS, VisAR enables physicians to find and reach their target destination more quickly - without the expense, footprint, and set up time of conventional navigation systems and robots.

"VisAR takes a lot of the guesswork out. It is going to open up navigation to a lot more patients, to help with improving minimally invasive surgery."

Dr. Michael Karsy, Neurosurgeon

Advanced Rendering

VisAR renders 2D and 3D digital images from any modality into a highly detailed hologram in real-time using the Novarad Graphics Engine. Using patented virtual tool technology with an integrated targeting system, the hologram is overlaid directly and accurately onto a patient's body.

Minimal Operative Footprint and Portable Hardware

 

Using optical code alignment, cameras, and sensors, VisAR maps both the patient and the surrounding environment from above, to the side, behind, or even underneath the patient using the hands-free, the untethered headset of the Microsoft HoloLens 2. The operative footprint is the surgeon's head.

Advanced Preoperative Planning

  • Colorize target organs, segment key anatomical features, or annotate pathology to create semi-transparent holograms of targeted anatomy. This allows for precise planning and execution of the procedure, even around difficult anatomy.
  • Place virtual incisions or mark virtual surgical guidance entrance point, trajectory, and location for instruments or needle placement. Procedures can be done both with open surgery and percutaneously.
  • Use instrument tracking and orthogonal views to more accurately navigate an instrument during surgery.
