  • Abstract: This work aims at reconstructing 3D ultrasound volumes from sequences of freehand images acquired with standard 2D probes without any expensive or cumbersome external tracking hardware. We extend our previous method based on deep learning to integrate and also learn from measurements of an inertial measurement unit (IMU). Our system is evaluated on a dataset of 600 in vivo ultrasound sweeps, yielding accurate reconstructions with a median normalized drift of 5.2% even on long sweeps with complex trajectories, hence paving the way towards translation into clinical routine.
