In Summary: Both the Ziehm Vision and the OEC Elite 9900 can serve all your fluoroscopic VASCULAR needs. However, the Ziehm Vision does offer a higher heat capacity tube along with a higher kW generator. The OEC Elite 9900 offers a 30fps vascular package compared to Ziehm’s 25 fps. The biggest difference between these two C-arm units is the Image Intensifier. The Ziehm system is using a direct digital plate that allows higher resolution and immediate image transfer. Even though this is a great feature that has revolutionized the C-arm industry, it also adds additional costs for maintenance and service. The plates used can be very expensive and will be difficult to locate on the used market. Pricing for the systems are pretty much the same, however x-ray parts seem to be more readily available for the OEC Elite 9900. For these reasons, we give the OEC Elite 9900 the edge and crown it the best C-arm.
