CBYON's SAVANT Suite makes surgeons see beyond skin and bones

San Antonio 26 September 2000CBYON Inc., a Silicon Valley-based provider of surgical software, has introduced the world's first set of Surgical Anatomy Visualisation And Navigation Tools, the SAVANT Suite, at the recent Congress of Neurosurgery annual meeting in San Antonio, Texas. Brain and spine surgeries are now possible with very accurate anatomical positioning and true 3D or three-dimensional visualisation.


"Patient anatomy does not look much like a Computed Tomography (CT) scan, when seen through an endoscope or microscope in surgery. Perspective 3D rendering combined with instrument tracking is therefore very useful to correlate the computer images visually to the real patient, as seen by the surgeon", stated John R. Adler, Professor of Neurosurgery at Stanford University. "Minimally invasive surgeries in the brain, spine and other locations will benefit greatly from CBYON's 3D technology, which means that the patients will suffer less pain, face fewer complications and experience faster recoveries."

Computerised Tomography (CT or CAT scans) and/or Magnetic Resonance Imaging (MRI) are used to build a virtual 3D model of the actual patient anatomy, prior to surgery. By pointing on the actual, live patient in the operating room, a semi-transparent computer rendering of the inside of the patient is displayed from the scalpel's perspective, allowing surgeons to see beyond the skin and bones which may obstruct the view of important blood vessels, tissues and pathologies.

"It is really 3D x-ray vision for surgeons", stated Ramin Shahidi, Ph.D., who is the Director of the Image Guided Laboratories at Stanford University, where the CBYON technology initially was conceptualised and prototyped. "Using patient specific data, the SAVANT Suite enables surgeons to visualise the patient's internal anatomy without the need for large incisions. It is now possible to fly through the virtual inside of the actual patient and localise the structures of clinical relevance. Informed surgical decisions can be made with great confidence because the system always shows the surgeons exactly where they are, together with the relative location of targets and critical structures."

CBYON Inc. is a private, venture capital backed surgical software company, developing state-of-the-art applications for neurosurgery, Ear/Nose/Throat (ENT) and spine procedures. Future applications include cancer biopsies and resections, cardiology and obstetrics-gynaecology. The software is optimised for the upcoming, future generations of Intel-based multi-processor PC platforms. Current versions run on powerful Silicon Graphics and DELL workstations with Windows 2000.
