This video presents the simulation of a robotic task that consists in synchronizing the 6-DOF motion of
a virtual ultrasound probe with a moving 3D ultrasound volume by tracking the displacement of a B-scan image of reference.
The out-of-plane motion is extracted from the speckle information contained in the ultrasound image,
and an image region tracking method is used to extract the in-plane motion.
Two independent visual control schemes are applied to automatically move the probe in order to track the full motion of the target B-scan.
The first part of the video shows the moving 3D ultrasound volume, the virtual ultrasound plane and
the observed ultrasound image when the motion tracking method and the probe control are not activated
and the second part shows the motion synchronization between the ultrasound probe and the 3D volume when the motion tracking method is activated.
