Three-dimensional (3D) ultrasound (US) imaging addresses the limitation infield-of-view (FOV) in conventional two-dimensional (2D) US imaging byproviding 3D viewing of the anatomy. 3D US imaging has been extensively adaptedfor diagnosis and image-guided surgical intervention. However, conventionalapproaches to implement 3D US imaging require either expensive andsophisticated 2D array transducers, or external actuation mechanisms to move aone-dimensional array mechanically. Here, we propose a 3D US imaging mechanismusing actuated acoustic reflector instead of the sensor elements for volumeacquisition with significantly extended 3D FOV, which can be implemented withsimple hardware and compact size. To improve image quality on the elevationplane, we introduce an adaptive-delay synthetic aperture focusing (AD-SAF)method for elevation beamforming. We first evaluated the proposed imagingmechanism and AD-SAF with simulated point targets and cysts targets. Results ofpoint targets suggested improved image quality on the elevation plane, andresults of cysts targets demonstrated a potential to improve 3D visualizationof human anatomy. We built a prototype imaging system that has a 3D FOV of 38mm (lateral) by 38 mm (elevation) by 50 mm (axial) and collected data inimaging experiments with phantoms. Experimental data showed consistency withsimulation results. The AD-SAF method enhanced quantifying the cyst volume sizein the breast mimicking phantom compared to without elevation beamforming.These results suggested that the proposed 3D US imaging mechanism couldpotentially be applied in clinical scenarios.
