Abstract
PURPOSE: Autonomous ultrasound imaging by robotic ultrasound scanning systems in complex soft uncertain clinical environments is important and challenging to assist in therapy. To cope with the complex environment faced by the ultrasound probe during the scanning process, we propose an autonomous robotic ultrasound (US) control method based on reinforcement learning (RL) model to build the relationship between the environment and the system. The proposed method requires only contact force as input information to achieve robot control of the posture and contact force of the probe without any a priori information about the target and the environment.
