Fig. 100 (abstract O74).From: International Society for Therapeutic Ultrasound Conference 2016Focal waveforms (z = 50 mm) obtained by direct modelling of propagation in the tissue phantom (blue curve) as well as by derating from free field water simulations (red curve for nonlinear derating, green curve for conventional derating). Results are shown for output levels corresponding to a 55 V and b 90 VBack to article page
