The Viatronix system, which is undergoing trials as an alternative to fiber optic endoscopy, has been installed in clinics run by Open Systems Imaging, of California, USA.
Viatronix, chaired by former astronaut Lieutenant General Thomas Stafford, said it hopes to introduce the system to Europe and other non-US countries later this year.
|The virtual colonoscopy system allows physicians to view the colon interior from any direction.|
The system enables a physician to navigate through the colon on a PC, using data from a helical CT scan.
The physician can view the interior of the colon from any direction, and can alter the direction of the light source.
The system includes a technique called 'translucent rendering', which can be used to study a suspected polyp and see its hidden structures.
Dr Mark Wax, Medical Director of Viatronix, of Stony Brook, New York, USA, said, "The trials are moving right along. Our system is demonstrating its effectiveness, versatility, and strong correlation with optical colonoscopy in the diagnosis of pre-cancerous colon polyps."
