A Row Column Addressed Handheld USB Ultrasound Probe for Real Time Biplane Imaging

3D ultrasound imaging for interventional procedures has a strong potential to improve accuracy and workflow. It currently involves heavy scanners and possibly navigation fusion equipment, that may impair procedure usability and ergonomics. We herein propose to ease the intervention by using a portable USB row-column addressed (RCA) probe allowing a biplane visualization for a precise needle placement and guidance. The resulting device is accurate and simple, and provides volumetric diagnostic information with a simple device pluggable on a tablet or smartphone.
