Intuitively Bionic

Introducing United Imaging's pioneering uAngio AVIVA, world-leading intelligent ceiling-mounted angiography system designed to be more than just a tool—it's your smart assistant in the operation room. With intelligent voice-control, vision, robotics, and imaging, uAngio AVIVA truly 'hears, sees, moves with exceptional flexibility, and thinks' revolutionizing how interventional procedures are performed. This groundbreaking innovation paves the way for a new paradigm in future procedures.

Intelligent Voice-Control

uAngio AVIVA features the world's first intelligent voice-control system, enabling medical staff to operate the device with voice command and stay focused on the procedure.

Voice detection is powered by a MEMS microphone array, with background noise suppression managed by an advanced neural network model. Movement control, image acquisition, image selection, and tools utilization are all effortlessly handled with voice command, enabling smooth, hands-free interaction in routine clinical scenarios.

Movement control, image acquisition, image selection, and tools utilization are all effortlessly handled with voice command, enabling smooth, hands-free interaction in routine clinical scenarios.

Intelligent Vision

uAngio AVIVA employs three sensors positioned above the operation room to capture real-time 2D images from multiple angles. These images are used to reconstruct a 3D model of the patient, equipment, and the entire operation room, creating a digital twin space known as uSpace. With this 3D intelligent vision, uAngio AVIVA autonomously identifies target areas, plans motion trajectories and adjusts exposure parameters. By actively sensing the operation room, this system heralds a new era of seamless human-machine collaboration.

Intelligent Movement

The 8-axis ceiling-mounted robotic system offers exceptional flexibility, allowing it to navigate freely through the complex environment of the operation room. This ensures full coverage of the lab space and enables easy tableside accessibility.

Clinical Flexibility Redefined

Conventional floor-mounted interventional systems have a limited range of motion and cover only a specific area. Ceiling-mounted interventional systems provide more movement but are confined to a longitudinal direction. The uAngio AVIVA system, with its innovative 8th axis, unlocks lateral movement, enabling coverage of the entire lab space. This enhanced flexibility distinguishes the uAngio AVIVA as a truly advanced robotic system.

uAngio AVIVA supports transverse movement, enabling easy access to the patient without moving the table. It allows the C-arm to reach the patient from any position (head, left, or right side), reducing patient movement during complex procedures such as EVAR and TAVI.

uAngio AVIVA's positioning flexibility enables clinical staff to select the optimal working position. With a 270° Z-rotation, the C-arm can reach all necessary imaging positions without disrupting the team's setup or requiring movement of the patient table.

uAngio AVIVA allows the clinical staff to optimize space usage for specific procedures. The 8-axis ceiling-mounted design significantly reduces floor space requirements in your lab, helps to prevent disturbances to equipment and instruments, ensuring the anesthesia zone remains unobstructed.

uAngio AVIVA's innovative C-arm back-folding design allows laminar flow to circulate more freely, enhancing the overall sterility of the environment.

Intelligent Imaging

Addressing the challenge of balancing low radiation dose with high image quality and minimizing contrast media dose while maintaining clarity, uVera IQ intelligent imaging technology delivers precise, high-quality images. It significantly reduces radiation and contrast media usage, providing care to both medical teams and patients.

Provide Accurate Insight with Low Dose

Decompose image into multi-frequency bands. Perform denoising according to noise property at different bands to keep structure information while improving SNR.

*SNR：Signal Noise Ratio, compares a level of signal power to a level of noise power. Higher SNR means better image quality, which noise displays less in images.

AI-enabled Coronary Enhancement ensures the same level image quality is achieved even with a 50% reduction in contrast media dosage.

Reduce subtraction artifacts by sub-pixel image registration both globally and locally, in real-time.

*MSE：Mean Square Error, stands for the difference between the mask image and filling image during matching. Lower MSE means a better matching and there will be less motion artifacts display on the image.
