Focal pressure waveforms generated by a source in the linear (top panel) and nonlinear (bottom panel) regime with a 10-cycle pulse. A short pulse, such as that used in intrinsic-threshold histotripsy is shown in the middle panel. Note the highly asymmetric waveform in the middle and bottom panels, typical for focused sources due to the combined effects of diffraction and nonlinear propagation.
