Mobile C-arm Opens the Way for Hybrid ORs

The hybrid edition features innovative flat-panel technology and delivers distortion-free images with over 16,000 shades of gray, with a resolution of 1,500 x 1,500 pixels. The square display format creates a significantly larger visible area, with up to 60% more information per X-ray than conventional image intensifiers; two 18.1" thin-film transistor (TFT) monitors present exceptional brightness and contrast.

A compact, 20 kW monoblock generator with a rotating anode delivers a variable pulse width between 4 ms and 50 ms; with up to 25 images per second, the hybrid edition also produces high-quality X-rays of moving objects, such as a beating heart. An active liquid cooling system keeps the operating temperature steady, preventing the generator from overheating and ensuring continuous imaging. The integrated injector interface synchronizes injection of contrast media with the imaging process, and a remote vision center features an operator panel that can be accessed via a touch-screen directly at the OR table, enabling direct control from the sterile environment. The Ziehm Vision RFD hybrid edition is a product of Ziehm (Munich, Germany).

“Ziehm Imaging RFD is far superior to other C-arms thanks to its exact and highly detailed reproduction of arteries, stenosis, balloons, and stents,” said Zahi Nassoura, MD, of the Providence Tarzana Medical Center (CA, USA). “It provides all the detailed information that we need for successful stent implants or transplants.”

The hybrid edition also comes with the SmartVascular software, which enables surgeons to create a digital subtraction angiography (DSA) at any time, automating all process steps from the actual DSA to roadmapping, thus allowing vascular procedures to be planned with minimum amounts of contrast media and shorter fluoroscopy times.
