Description

 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.

Highlights:

  • For demanding interventions, a range of finely tuned components deliver outstanding image quality.
  • Smart Dose provides best image quality with minimum dose.
  • New dimension in user friendliness. Adapted to clinical workflows with new levels of intuitive guidance.
  • Precision matters. A reliable and powerful solution for the OR.
