3D Ultrasound Image Guidance and Therapy Through the Rib Cage with a Therapeutic Random Phased Array

Therapeutic and imaging capabilities of a 1 MHz random phased array are described. Multiple simultaneous foci were generated and steered in simulations as well as experimentally. In imaging mode, the random phased array was integrated with Verasonics system via custom-built connectors to acquire raw RF data. Imaging was implemented using synthetic aperture beamforming to produce 3D images of the region of interest. Ex vivo rib phantoms were imaged both in simulation and experimentally in water bath.
