A Simplified 3D Ultrasound Freehand Imaging Framework Using 1D Linear Probe and Low-Cost Mechanical Track
Ultrasound imaging is the most popular medical imaging modality for
point-of-care bedside imaging. However, 2D ultrasound imaging provides only
limited views of the organ of interest, making diagnosis challenging. To
overcome this, 3D ultrasound imaging was developed, which uses 2D ultrasound
images and their orientation/position to reconstruct 3D volumes. The accurate
position estimation of the ultrasound probe at low cost has always stood as a
challenging task in 3D reconstruction. In this study, we propose a novel
approach of using a mechanical track for ultrasound scanning, which restricts
the probe motion to a linear plane, simplifying the acquisition and hence the
reconstruction process. We also present an end-to-end pipeline for 3D
ultrasound volume reconstruction and demonstrate its efficacy with an in-vitro
tube phantom study and an ex-vivo bone experiment. The comparison between a
sensorless freehand and the proposed mechanical track based acquisition is
