Schematic of experimental setup. HIFU was focused onto the chicken breast fillet in degassed water. The water temperature was kept at approximately 35 °C. A linear ultrasound probe was used to acquire RF data for B-mode images during HIFU exposure. The HIFU focal point was set at 50.0 mm from the probe surface in the depth direction and 12.5 mm from the left edge of the B-mode images in the lateral direction
