Peak positive and negative pressures at the focus (z = 50 mm) versus transducer output voltage. Propagation is simulated in water (black curve) and in a tissue phantom (blue curve). Horizontal and vertical arrows illustrate nonlinear derating by scaling the source amplitude (red curve) and conventional derating by scaling the focal pressures (green curve)
