University of Lübeck develops AI-driven robotic ultrasound system

Researchers at the Institute for Robotics and Cognitive Systems at the University of Lübeck are developing ARUS, an automated robotic ultrasound system designed for diagnostic applications. The project aims to make ultrasound scans more standardized, reproducible, and independent of the individual operator's experience.

The system utilizes artificial intelligence to map a patient's body surface and position. Based on this data, the AI plans specific examination paths, which a robotic arm then follows to guide the ultrasound probe. By recording the exact position and orientation of the probe, the system ensures that subsequent examinations of the same patient are comparable.

Development of ARUS addresses demographic challenges, including an aging population requiring more diagnostic imaging and a projected shortage of medical professionals due to retirements. The project is scheduled to be presented at the Lübeck AI Experience Day on November 10, 2026.
