A highly advanced neurosurgical microscope with integrated digital augmented reality (AR) supports critical intrasurgical decisions.

The Leica Microsystems (Wetzlar, Germany) ARveo AR neurosurgical microscope features a built-in 31-inch, 4K three-dimensional (3D) monitor and a cart-mounted 55-inch monitor that enables the entire operating room team to follow the procedure in 3D. The highlight of the system is GLOW AR technology, a comprehensive visualization solution that provides flexible viewing options by combining a high contrast indocyanine green (ICG) fluorescence signal and the white light image to provide a single view of cerebral anatomy in natural color, augmented by real-time vascular flow.

The result is a single, real-time view that obviates the need to recall and reconcile black and white near infrared (NIR) blood flow video with the natural anatomical view. The full depth perception and lack of dark peripheries through image homogenization support clear spatial orientation. In addition, GLOW AR provides flexible viewing options, such as digital image injection and three dimensional (3D) displays, as well as wireless sharing beyond the operating room (OR), such as by live streaming and by HD recording. Images can also be transferred into the patient electronic medical record (EMR).

“ARveo with integrated GLOW AR takes surgical visualization to the next level by placing the latest digital imaging technology at the service of medical progress in the best possible way,” said Markus Lusser, President of Leica Microsystems. “Maximum visual information about cerebral anatomy and physiological processes; this is what neurosurgeons have told us they need most when performing life-changing neurosurgical interventions. The augmented visual information empowers decision-making and supports optimal patient outcomes.”

“At Leica Microsystems we have been leading the way in optical and fluorescence imaging innovation for decades. Now with ARveo and integrated GLOW AR technology we have brought all of our expertise together to deliver what neurosurgeons have always wanted: a single, comprehensive view of the surgical site,” said Maxim Mamin, MD, vice president of the medical division at Leica Microsystems. “They don't need to switch views and reconcile information, they can simply activate the digital imaging technology they need at any moment of a surgery and instantly augment their visualization.”

The ARveo microscope is also ergonomically designed to adapt to the surgeon’s preferred style of work and body frame by providing a choice of binoculars, all with 360° rotation and versatile positioning of the optics carrier, as well as optimal visualization for the rear assistant with independent fine focus. Lightweight handling and an extensive range of movement of the optics carrier limits potential strain from harsh movements, as does the flexible use of long instruments thanks to the large 600 mm working distance.
