Cios Alpha

In image-guided surgery, image quality and dose often come at the expense of one another. Dose reduction often means lower image quality – while higher dose can mean potential health risks for patients, surgeons, and staff.

Cios Alpha® is a high‐definition 2D mobile C‐arm designed to give surgeons certainty in these matters. Thanks to Retina technology for optimal images, CARE technologies for the right dose in each case, and intelligent power management, it delivers the perfect balance between image quality and dose.

  • Excellent images, right dose
  • Easy handling, smooth workflow
  • Extended capabilities, smart growth
