From Freehand Demonstrations to Autonomous Robotic Ultrasound: An Anatomy-Anchored Learning Framework

From Freehand Demonstrations to Autonomous Robotic Ultrasound: An Anatomy-Anchored Learning Framework

Summary

This research introduces an anatomy-anchored imitation learning framework for robotic ultrasound scanning. The framework combines anatomy-guided probe placement with learned ultrasound navigation, enabling autonomous scanning with high task success rates. The approach reduces reliance on third-person vision and achieves 96%, 94%, and 88% success in kidney, gallbladder, and liver standard-plane acquisitions, respectively, with significant improvements over baseline models.

Editorial context

This paper presents an anatomy-anchored imitation learning framework for robotic ultrasound scanning, demonstrating improved task success rates and reduced reliance on third-person vision. The approach combines anatomical guidance with egocentric vision and force feedback, achieving high success rates in standard-plane acquisitions and radial artery sweeping.

On 16 unseen participants, task success reaches 96%, 94%, 88%, and 94% for kidney, gallbladder, and liver standard-plane acquisition and radial artery sweeping, respectively. Compared with a fine-tuned pi_0 model, success on the abdominal tasks improves by 10-42 percentage points, with lower time-to-target, peak contact force, and trajectory jerk.
