Towards MRI-Based Autonomous Robotic US Acquisitions: A First Feasibility Study

Abstract: Robotic ultrasound has the potential to assist and guide physicians during interventions. In this work, we present a set of methods and a workflow to enable autonomous MRI-guided ultrasound acquisitions. Our approach uses a structured-light 3D scanner for patient-to-robot and image-to-patient calibration, which in turn is used to plan 3D ultrasound trajectories. These MRI-based trajectories are followed autonomously by the robot and are further refined online using automatic MRI/US registration. Despite the lo… Show more

“…A commercial robotic manipulator has been released (LBR Med, KUKA AG, Augsburg, Germany) which is suitable for use in clinical environments due to its conformity with medical device safety (ISO 60601) and medical software regulations (ISO 62304). Current research suggests that such robots can be applied in diagnostics to autonomously perform aorta measurements [16], in combination with previously acquired MRI scans to autonomously find standard view-planes [17] and in intraoperative procedures to autonomously track surgical tools [18], amongst others. Whilst such robotic platforms allow for great flexibility through a large workspace and high manipulability, the use of large-scale robotic manipulators can pose various disadvantages for clinical integration.…”

“…Great thanks to Savatore Virga and Marco Esposito for their work on the iiwa_stack project [23] which has been used for our test on real hardware as well as in simulation. On top we improved the rosjava support for ROS actions as well as the support for applying velocity constraints for the KUKA LBR iiwa and ported TF to java.…”

“…Our simulated environment was built in Gazebo [27] -a ROS simulation software -and consisted of a KUKA LBR IIWA simulated robot [28], to which we added the gripper, camera, table and parts. Simulated depth images were created with the Gazebo depth camera plugin.…”
