Description:

As the basic technology platform for all mobile imaging systems in the Ziehm Vision family, this C-arm suits the broadest spectrum of surgical applications. Thanks to its liquid cooling system, the Ziehm Vision is designed for continuous use even during longer procedures. Packed with leading-edge functionality, the Ziehm Vision sets a standard in mobile imaging and ensures minimized dose levels.
