Abstract

A first experimental verification of the benefit of dual-mode ultrasound array (DMUA) systems for noninvasive surgery was presented. The feasibility of using image-based feedback for refocusing for targeting tissue structures while avoiding critical obstacles such as the ribs was presented. The target is partially obstructed by the rib cage, which limits the access and distorts the geometrically-focused high-intensity focused ultrasound (HIFU) therapeutic beam. The result shows that the power delivered at the target can be increased by several fold without a corresponding increase at the rib locations.
