Block diagram and schematic of the HMI experimental setup ex vivo. (a) pulse-echo transducer, (b) HIFU transducer attached to (d) the 3D positioner and (c) a coupling cone filled with degassed distilled water. (g) The specimen was cased between (f) two gel layers (in the case of the phantom, there were no layers, only uniform gel material), and was submerged in (e) degassed PBS. In order to reduce potential reflections, (h) an absorber was placed on the bottom of the glass beaker tilted by a height amount (i) and an angle (theta) to avoid specular reflections
