A Less Expensive Option for Hybrid ORs
High-quality angiographic X-ray imaging systems are a key component when planning a hybrid operating room. For this reason, large fixed angiography systems are generally considered when creating these rooms, because the image quality has traditionally been much better than mobile C-arms. However, advances in detector technology and new imaging software have greatly improved mobile C-arm capabilities over the last few years.

Fixed systems also use liquid cooling systems to prevent overheating during prolonged imaging. In March, Ziehm introduced its newest mobile C-arm, the Vision RFD, with a liquid cooling system to allow continued use during long procedures. The company hopes the system will compete as a less expensive alternative to fixed systems in hybrid ORs.

The new system uses flat-panel technology to deliver distortion-free images with more than 16,000 shades of gray and a resolution of 1.5 by 1.5 k pixels. The detector is not affected by magnetic fields, so it also produces distortion-free, detail-rich images when close to magnetic resonance (MR) scanners. The square display format creates a significantly larger visible area with up to 60 percent more information per X-ray than conventional image intensifiers.

Another feature usually only found on fixed systems is a contrast media injector interface to synchronize injection of contrast with the imaging process. The Vision RFD offers this same interface. The new Ziehm system was recognized in February with Frost & Sullivan’s European Product Leadership Award 2011 in the interventional radiology category.
