Ziehm Vision RFD 3D

The revolution in 3D imaging

Healthcare providers are challenged to cut costs, meet the needs of an aging demographic, improve the accuracy of clinical outcomes and reduce X-ray exposure during surgical procedures. The answer – led by the Ziehm Vision RFD 3D – lies in balancing cost efficiency with improved patient care, shorter hospital stays and less-invasive approaches. This groundbreaking mobile 3D C-arm helps to improve surgical outcomes and patient satisfaction while optimizing costs. Building on more than 10 years of experience in 3D imaging, the Ziehm Vision RFD 3D features cutting-edge CMOS technology, bundling 2D and 3D functionality for greater intraoperative control, reducing the need for postoperative CT scans, and costly corrective surgeries.

This mobile C-arm is thus ideal for high-end orthopedic, trauma and spinal interventions as well as for highly specialized maxillofacial and cochlear procedures.

The system Ziehm Vision RFD 3D is now available in the CMOSline1,2 premium edition. All CMOSline systems come with a Ziehm Imaging CMOS detector and the groundbreaking dose reduction technology Beam Filtration3. This combination allows for excellent image quality with a lower dose.
