The hind legs of guinea pigs were exposed to 0.75-MHz ultrasound of different intensities in an attempt to define a threshold for previously observed bubble formation. For continuous-wave ultrasound, the threshold appears to be around 110 mW cm-’, whereas for pulsed ultrasound 2-ms pulse and 2-ms gap the spatial average pulseaveraged intensity threshold… CONTINUE READING
