For cranial and spinal neurosurgery, VISIUS Surgical Theatre features a high-field MR or multi-slice CT scanner that travels into the OR on demand to provide intraoperative images of exquisite quality ­– without introducing additional risk to the patient –  delivering real-time information to clinicians while preserving optimal surgical positioning, access and techniques. 

With integrated tools and technology for specific clinical applications, the VISIUS Surgical Theatre is an optimized environment for intraoperative imaging and image guided treatment.

Better Vision 

MR, CT and fluoroscopic imaging are available on demand in the OR. 

More Precision

Integrated technologies maintain optimal patient positioning for surgery and true intraoperative imaging.

Greater Utility

Two- and three-room multifunctional theatres are designed for image guided and non-image guided neurosurgery. With a single MR scanner for diagnostic and intraoperative imaging, and a technology platform that enables endovascular procedures, the VISIUS Surgical Theatre is a flexible, scalable solution for a wide range of clinical applications.

Over the last two decades, clinicians, scientists and engineers have been developing intraoperative imaging systems to improve surgical treatment. Today, leading neurosurgical hospitals indicate that in over 40% ^1,2,3 of all cases, the surgeon chose to modify their approach based on new information from intraoperative MR imaging that would otherwise not have been available until after completing the procedure. Furthermore, in over 55%^1-6 of glioma cases, additional brain tumor was identified and resected after intraoperative MR. These centers report achieving a 30 point increase^1,2,7,8 in the percentage of patients with gross / total resection when intraoperative MR was used. Considering that “improved outcome among adult patients with hemispheric LGG [glioma] is predicted by greater EOR [extent of resection]”⁹, VISIUS Surgical Theatre is making a significant difference in neurosurgery today.

Real-time Information. Enhanced Decision-making.

The VISIUS Surgical Theatre is a seamlessly integrated environment that provides surgeons with images and data at any time –b efore, during or after a procedure – without moving the patient.

With high-field intraoperative MR imaging, the surgeon is able to visually differentiate tumors from healthy brain tissue and accurately identify eloquent areas and white matter tracts. Without moving the patient from the table, the surgeon can assess brain shift, refine the surgical plan, and visualize the extent of tumor resection prior to closing the surgical site.

Intraoperative MR Imaging without Compromise

With a ceiling mounted MR that travels into the OR on demand, patient transport for imaging is eliminated. Anesthesia and patient monitoring remain safe and secure and the sterility of the surgical environment is maintained.

When not in use for intraoperative imaging, the MR exits the OR completely, enabling the surgeon to use standard surgical instruments. Specialized tables, head fixation devices and imaging technologies preserve preferred surgical techniques and enable optimal patient positioning for surgical access. 

Safe & Efficient Imaging On Demand

When the surgeon requires imaging in a VISIUS Surgical Theatre, a high field (1.5 T and 3T) MR on ceiling rails travels to the patient for scanning. Safety interlocks and an advanced collision detection system control the movement of the MR for the safety of the patient and clinical team.

Optimized for Intraoperative Imaging 

The MR is customized for imaging in multiple locations with patented shimming technology. The system supports DTI, MRA, MPRAGE, diffusion and 3D T1/T2 sequences with minimal acquisition time for intraoperative imaging.

Imaging coils are specifically designed for intraoperative imaging during neurosurgery. The flexible two-piece design allows full surgical access and enhances patient comfort. The posterior element can be left in position during surgery while the anterior section can be easily positioned and removed at any time, streamlining the transitions between surgery and imaging. The ability to conform the coil to the anatomy and position it independent of the angle of the patient provides an enhanced signal-to-noise ratio for exquisite quality images.

Optimizing Patient Positioning

Operating tables and head fixation devices are specifically designed to work together with coils to enhance images and optimize patient positioning for surgical access and imaging. The MR-safe head fixation device enables adult and pediatric patients to be placed in prone, supine and lateral positions. Its low profile design makes it easy to position the head in the MR iso-center for optimal imaging, and allows a prone patient to be imaged with the head lower than the table. 

Fully functional, MR-compatible OR tables are uniquely designed for surgery and intraoperative imaging of the head, neck and spine. A removable OR table(available in US and Canada only) provides added flexibility to the VISIUS Surgical Theatre enabling surgeons to interchange OR tables for specific procedures.

2. Adapter for stereotactic procedures
3. Fixed and removable OR tables

Unique safety, workflow, room control and data management systems – specifically designed for the intraoperative MR environment – are built into every VISIUS Surgical Theatre. 

With VISIUSmatrix™, the clinical team can adapt the OR to suit the requirements of each surgeon and procedure, with centralized control over:  

• Room lighting 
• Routing, recording, streaming and archiving of video streams
• Internal and external communication using  voice and data
• Workflow management
• Power to devices in the OR to prepare for imaging

Every VISIUS Surgical Theatre features a custom RF shielding system that preserves image quality. Unique MR access doors, shielded openings and electronic filters maintain an RF-quiet environment during imaging.

Intraoperative CT Solution

For cranial and spinal neurosurgery, VISIUS Surgical Theatre can be configured with a multi-slice CT scanner that travels to the patient on demand to provide intraoperative vision to the surgeon and enhance treatment precision without patient transport.

With precision movement, the 20-, 40- or 64-slice CT scanner enters and exits the OR traveling on floor rails without compromising image quality or exam speed. A unique rail cover minimizes tripping hazards, eases cleaning and minimizes liquid ingress.

A Platform for Neurosurgery and Endovascular Interventions

A Platform for Neurosurgery and Endovascular Interventions

When a VISIUS Surgical Theatre is equipped with a ceiling-mounted MR scanner and an integrated x-ray angiography system, it becomes the only OR in the world in which patients can be scanned in the MR, treated percutaneously or surgically on the angio system, and scanned again in the MR to verify treatment – without ever leaving the table.  

The ability to perform open surgical applications and catheter-based treatments in this environment creates opportunities for multiple departments to collaborate on its investment and to optimize its utilization.
