Brainlab neuronavigation combines ease of use with extended functionality tailored to surgeons’ needs

Touchless surface matching registration with Z-touch®

Time-Saving Registration1

Regardless of the patient’s position, Brainlab Cranial Navigation offers multiple techniques for referencing them to the system. Z-touch® and Softouch® are based on surface matching, making patient registration easy by simply touching the patient’s skin with either a pointer or a laser. As both devices register existing diagnostic CT and MR images without headsets or markers, additional registration scans can be avoided, helping to reduce neuronavigation costs and radiation exposure to the patient and O.R. team.

  • Pointer registration with or without markers
  • Touch-sensitive surface matching with Softouch
  • Contact-free surface matching with Z-touch
  • Combined surface matching registration
  • Pre- and intraoperative landmark registration

Approach Planning

Informed approach planning requires consolidated clinical data. Cranial Navigation summarizes relevant and detailed anatomical information in one dedicated view helping surgeons identify the optimal craniotomy before making the incision.

  • Automatic segmentation of skin, bone, cortical vessels and cerebrum
  • 3D preview of the lesion and critical structures before opening the skull
  • Virtual scalpel simulates craniotomy and creates a bone flap object that can be saved for documentation
  • Approach planning in 3D and correlated inline or axial, coronal, sagittal navigation views provides spatial orientation
Detailed visualization of relevant anatomical information in one dedicated view
Dynamic 3D view provides context around the tool tip to help with orientation

Easy-to-use Navigation

When navigating, distraction-free concentration is essential. Detailed visualizations are tailored to show only clinically relevant data allowing the surgeon to focus on what’s necessary for their work. Automated data selection and layout composition are designed to reduce screen interaction, making Cranial Navigation even more user-friendly.2

  • Smart Approach view dynamically adapts and zooms according to resection progress
  • Overlay mode with fused CT and ultrasound data consolidates anatomical details
  • Dynamic 3D view provides 3D context around the tool tip to help with orientation
  • User interface automatically displays patient data in the most suitable layout

Vascular Navigation

Cranial Navigation Angio3 helps surgeons to identify feeding and draining veins on navigated digital subtraction angiography (DSA) data or locate a nidus object with dedicated view layouts. Co-registration of angiographies and subsequent neurovascular contouring adds clinical context from anatomical 3D data contributing to improved orientation.2

  • Combines co-registered angiography pairs and navigated MR/CT reconstructions
  • Interactively displays dynamic color-coded contrast flow projections to assist with surgical target identification and analysis
  • Visualizes 2D DSA data as Color Intensity Projection (CIP) to help identify feeding and draining vessels
  • Displays nidus object on navigation data
Combination of co-registered angiography pairs and MR reconstructions unites blood flow and anatomical information
Navigation-ready pre-calibrated Disposable Stylet

Navigated Disposable Stylet

The Disposable Stylet is designed for the navigated placement of shunts or ventricular catheters in neurosurgery, enabling their freehand placement. The incorporated passive marker geometry is automatically recognized by the navigation camera, allowing for instant use.

  • Navigation-ready pre-calibrated tool
  • Shunt/catheter vendor independent
  • 1.1 mm diameter, 165 mm length

Robotic Biopsy Alignment

The Cirq alignment software facilitates intuitive manual arm positioning while the robotic module performs automatic trajectory alignment. Trajectories can conveniently be defined using Elements Trajectory Planning or the on-the-fly instrument offset acquisition within Cranial Navigation.

  • Automatic alignment to planned biopsy trajectory after manual arm positioning
  • Cirq alignment software provides visual guidance towards region of interest
  • Biopsy anchor for the skull adds stability to the setup

VarioGuide frameless universal instrument holder and pre-calibrated Disposable Biopsy Needle

VarioGuide Alignment

Surgeons can target pre-planned trajectories with Brainlab VarioGuide®. The frameless universal instrument holder combined with the VarioGuide alignment software offer continuous position feedback and precise step-by-step workflow guidance. For navigated biopsy, pre-planned trajectories can be seamlessly reached with the pre-calibrated Biopsy Needle.4

  • Bridges gap between head frame and freehand
  • Flexibly adapts to various instrument sizes (Ø 1.8 – 8 mm)
  • Disposable pre-calibrated Biopsy Needle (Ø 1.8 mm) seamlessly integrates into navigation workflow

Augmented Reality Visualizations

Augmented reality has become an essential technology in neurosurgery, virtually showing surgeons what lies beneath the surface. Microscope Navigation digitally overlays the planned surgical target and surrounding structures as semi-transparent objects onto the real patient anatomy. These visualizations provide anatomical insight and spatial orientation throughout the procedure.

  • Provides meaningful context about the surgical situation without having to look away from it
  • Maintains navigation accuracy and corrects initial patient registration based on anatomical landmarks
  • Navigation-controlled robotic movement supports ergonomic and accurate alignment to navigated instruments and anatomical landmarks
  • Seamlessly integrates with major surgical microscope vendors
  • Auto-detects connected microscopes, minimizing setup effort2

Live Intraoperative Imaging

Ultrasound Navigation provides real-time intraoperative imaging that complements cranial image guidance. With a small footprint and minimal interruption of the surgical workflow compared to other imaging modalities, it’s a suitable addition for almost every neurosurgical suite.

  • Overlays real-time ultrasound images in 2D or 3D
  • Provides accurate orientation as well as updates on resection progress
  • Allows for visualization and assessment of brain shift
  • 3D scanning of the cavity helps identify residual tumor and helps achieve the planned extent of resection

Automatic Image Registration

Automatic Image Registration (AIR) is the fundamental technology for seamless integration of intraoperative MRI (iMRI) images with image guided surgery. AIR adds intraoperatively acquired data to surgical navigation, optimizing the workflow while maintaining the preoperative surgical plan.

  • Eliminates need to access anatomical landmarks
  • Markers integrated in headholder enable accurate image registration
  • AIR iMRI available for various MR scanners
  • Universal AIR technology available for integration of other imaging devices such as CT, rotational angiograph and cone-beam CT5
