Penn Neurosurgery Goes 3D

Released: 2/16/2006 2:20 PM EST

Newswise — Neurosurgeons and neuroradiologists at the Hospital of the University of Pennsylvania are now using virtual reality, three-dimensional (3D) imaging for surgical planning, evaluation, and education. Prior to walking into the Operating Room, Penn neurosurgeons can now use a Dextroscope® to create interactive, 3D images of their patient's brain to plan the best surgical approach in dealing most effectively with a diagnosed condition.

"This superior technology provides remarkable advances in imaging and surgical planning for brain and skull-base tumors and epilepsy," said Sean Grady, MD, Chair of the Department of Neurosurgery at Penn. "It allows us to look at the brain in ways similar to how we would during surgery, and then plan the best technique for each patient before we even begin. This is of great benefit to the patient, because it results in a less-invasive surgical process, using smaller incisions."

The Dextroscope works by fusing multi-modality images - such as CT and MRI - into 3D volumetric objects that, when viewed through special stereoscopic goggles, are transformed into virtual reality, 3D images. The suspended brain images give surgeons a detailed advance visualization of the complex anatomical relationships and pathology of the patient's brain. Further, the images can be easily manipulated by the surgeons, in real time, by using a control mechanism and stylus that work in conjunction with the Dextroscope. Such hands-on interaction - including "virtual drilling" for surgical-path planning and tools to measure linear distances and curved surfaces in 3D space - permits the surgical team to plan and "test" their exact clinical approach.

The Dextroscope also serves as an educational tool for neurosurgeons at any level of expertise, teaching both basic anatomy and advanced surgical techniques. With this technology, the user can practice a procedure over and over.

"The advanced imaging and planning capabilities that this technology offers is enhancing how we perform neurosurgery here at Penn," said Grady.

Penn's Department of Neurosurgery covers the entire spectrum of disorders that impair the central and peripheral nervous system. Performing over 2,000 operations each year, the Department provides superb patient care by embracing new technologies and integrating research with clinical practice.
