Dextroscope(R) Changes the Neurosurgical Planning Paradigm

3D Virtual Reality System Puts Patients Images in the Surgeon's Hands

Six Renowned Institutions - Stanford University Hospital & Clinics, Hospital of the University of Pennsylvania, St. Louis University Hospital, University of Medicine and Dentistry of New Jersey, Cornell University -NY Presbyterian Hospital - Johns Hopkins University Hospital - Among the First to Utilize Breakthrough Imaging Technology in the U.S.A.

Imagine....a technological which surgeons can virtually interact with imaging data and simulate their approach...all before a surgery ever begins. Well, it's here and now, thanks to Dextroscope.

PRINCETON, N.J.--(HSMN NewsFeed)--Aug. 16, 2006--The Bracco Group Dextroscope is a virtual reality system which uses computer software to integrate tomographic images from CT and MRI into true 3D volumetric objects that can be viewed stereoscopically. A surgeon can perform a "virtual drill", if you will, by taking patient-specific images, and literally, (or, rather, virtually) hold them, turn them, work with them, and evaluate different surgical approaches from any angle, long before ever laying a hand on the patient.

Dextroscope provides a deeper understanding of complex anatomical relationships and pathology for surgical planning and evaluation. Dextroscope utilizes two six-degree-of-freedom (6D) positional controllers, one in each hand, that work as extensions of the surgeon's hands, providing the ability to interact with patient images. In addition to pre-surgical planning, surgeons can show and explain to patients exactly what's going on, why, and what they plan to do to correct the problem.

"Dextroscope adds a higher level of sophistication to the most complex and demanding types of neurosurgery, while taking much of the mystery and uncertainty away," explained Joe Balogh, General Manager, Volume Interactions. "Ultimately, Dextroscope is an 'insight' resource. It gives surgeons a clearer roadmap to follow which may improve their surgical confidence."

The University of Medicine and Dentistry of New Jersey (UMDNJ) is one of the first medical institutions in the United States to work with Dextroscope. At UMDNJ, neurosurgeons are now able to use this system to diagnose and treat neurological, temporal bone and spine disease, disorder and injury such as brain tumors, complex cerebral aneurysms, and neurological trauma.

"We can look at the brain or spine from any angle that we want, either in two dimensions or in three dimensions," said Michael Schulder, MD, Vice Chairman of the Department of Neurological Surgery, UMDNJ-New Jersey Medical School. "We can rotate the model any way we want. And it's really like holding an actual model of a brain or a spine in your hand - except in this particular case, it's of a particular person. It's of the patient who's about to undergo surgery."

The other major medical institutions that have begun utilizing Dextroscope in the United States include: The Hospital of the University of Pennsylvania, Cornell University /New York Presbyterian Hospital, Stanford University Hospital and Clinics, St. Louis University Hospital, and Johns Hopkins University Hospital.

"This is breakthrough visualization technology, and it's been embraced by the institutions that are on the leading edge of academic medicine," said Balogh. "Dextroscope must be experienced to be believed. Being able to easily and intuitively visualize and interact with your patient's imaging data in true stereoscopic 3D is a unique experience. It literally adds a new dimension to surgical planning and medical education."

Dextroscope can be used by an individual or a small team of people who wish to review data simultaneously. It is ergonomically designed, so an individual can perform hours of delicate work without strain. A user is able to comfortably rest his or her arms, and can then "hold", view and interact with the images right in front of their eyes.

The system was developed by Volume Interactions, a Singapore-based developer of high-tech solutions for medical applications, specifically neurosurgery and advanced diagnostic imaging, which is part of the Bracco Group. It was formally introduced to the U.S. market in April 2006.
