Ceiling-mounted C-arm uAngio® AVIVA CX

with flat panel detectorwith integrated video monitor

Overview
United Imaging's uAngio® AVIVA CX is a ceiling-mounted angiography system integrating voice control, multi-sensor vision, robotics and AI-driven imaging to support interventional cardiology, neuro and radiology procedures. The system enables flexible, tableside access and automated imaging workflows to streamline procedures and reduce manual adjustments.

Key features

• Intelligent Voice-Control: MEMS microphone array with background-noise suppression via neural network; supports voice commands for movement, image acquisition and tool control to enable hands-free operation during procedures.
• Intelligent Vision (3D Intelligent Vision): Three sensors capture multi-angle 2D images to reconstruct a 3D digital twin (uSpace) of patient, equipment and OR; supports autonomous target identification, trajectory planning and exposure optimization.
• Intelligent Movement: 8-axis ceiling-mounted robotic C-arm delivering extensive flexibility including lateral/transverse travel and ±135° Z-rotation for full lab coverage and simplified tableside access.
• Intelligent Imaging (uVera IQ): AI-assisted imaging balancing low dose and high image quality; features multi-frequency denoising, real-time pixel shift to reduce motion artifacts and VeraCT HD for high-resolution 3D imaging.
• uSpace AI capabilities:
  • uSpace Auto Positioning — proactive target localization and path planning for precise positioning.
  • uSpace VeraCT — isocenter positioning with virtual rotation test runs for simplified 3D acquisition.
  • uSpace Isocenter Tracking — maintains target isocenter (e.g., heart) centered in view.
  • uSpace Auto SID — real-time detector-to-patient distance optimization to improve image quality and reduce dose.
  • uSpace Auto Parameters — automatic identification of patient 3D model and optimization of acquisition parameters (kV, mA, ms, etc.).
• Robotics advantages: 8th axis enables lateral movement for full lab coverage, reduced patient repositioning, flexible staff working positions, minimized floor footprint and back-folding C-arm design to support laminar flow and sterility.
• Imaging enhancements: AI-enabled coronary enhancement (clinical trial: up to 50% contrast reduction), Dynamic Coronary Roadmap (motion-compensated overlay), uStent Live and multi-modality fusion for enhanced visualization and navigation.
