Ziehm Vision² FD

Ziehm Vision² FD delivers high-quality imaging with low dose exposure on a footprint of just 0.8 m². It features a compact C-arm and monitor cart with an intuitive touchscreen user interface as well as two 19” flatscreen monitors. It has a high-resolution CCD camera that detects over 4,000 shades of gray. The monoblock generator’s unique liquid cooling system (Advanced Active Cooling) is specially designed for extended use in operating theaters, making the Ziehm Vision² ideal for a wide range of clinical applications such as general surgery, orthopedics, and traumatology.
