Ziehm Vision R

Equipped with a rotating anode embedded into a powerful monoblock generator, this c-arm achieves highest image quality at lowest possible dose. These properties, in combination with the Advanced Active Cooling system, significantly extend operating times, while delivering superb image quality. This makes the Ziehm Vision R particularly suited for demanding procedures in cardiology and vascular surgery including PTCA, PTA and EVAR. The compact design of this mobile C-arm together with its unmatched ease of use benefit both surgeons and operating staff.
