Step into the new dimension of spine surgery with

Augmented Reality Surgical Navigation technology

    As more and more spine surgeries are performed annually, it is our mission to help surgeons treat their patients better. Today many spine surgeons are already experiencing the confidence and precision that comes with performing complex spine cases in Philips cutting edge Hybrid OR. Now we are on a research journey to further innovate intra-operative navigation for complex open and minimally-invasive spine surgeries with our new Augmented Reality Surgical Navigation technology.

    Why push the limitations of navigation for complex spine procedures?

    Our Spine suite solution with XperCT cone-beam CT and large field-of-view 2D and 3D images is a perfect example, which offers remarkably detailed insights during each phase of a spine procedure. Building on that strong base and our intensive collaborations with medical professionals at the forefront of spine procedures, we are aiming to take image guidance technology to the next level of precision. Our latest advance opens up new possibilities in performing open and minimally-invasive spine procedures by bringing imaging and Augmented Reality Surgical Navigation together in one solution.

    How does Augmented Reality Surgical Navigation work?

    Combines 3D X-ray imaging and optical imaging in a unique augmented-reality view of the inside and outside of a patient

    Our new Augmented Reality Surgical Navigation technology is being developed to add additional capabilities to manage X-ray dose (1 in picture above). The technology uses high-resolution optical cameras integrated in the flat panel X-ray detector (2) to image the surface of the patient. It then combines the external view captured by the cameras, and the internal 3D view of the patient acquired by the X-ray system, to construct a 3D augmented-reality view of the patient’s external and internal anatomy (3). This real-time 3D view of the patient’s spine in relation to the planned path, aims to improve procedure planning, surgical tool navigation and implant accuracy, as well as reduce procedure times.


    The Augmented Reality Surgical Navigation technology has the following characteristics:

    • Displays 4 optical views of planned path on patient. Optical navigation technology reduces use of X-ray dose in the OR
    • Provides high-resolution 3D volume rendering from an acquired cone beam CT scan
    • Offers intra-operative 3D imaging for navigation and validation
    • Automatic patient motion compensation with non-invasive markers, eliminating use of invasive reference frame
    • Automatic device tracking to follow progression of the needle towards the pedicle

    X-ray during navigation

    • Radiation dose exposure for full procedure ranged from 0 to 1.1 μSv for operating surgeon
    • No post-operative CT as XperCT was used for clinical evaluation
