Figure 1.

(a-b) pFUS guidance to the mouse pancreas using a therapeutic transducer fitted in a custom cone and filled with degassed water ((a) side-view and (b) top-view). The transmitted ultrasound waves are produced by a function generator, amplified through the amplifier at a constant gain and emitted from the transducer face to eight evenly distributed foci throughout the mouse pancreas; (c) The typical waveform and (d) 2D pressure map measured (full width half-maximum area for pressure) at a focal area (10mm long × 1.5mm diameter).
