Lowest ultrasound setting
WebTo stay below the maximum ultrasound output power, we set the highest MI to 1.1 in our ultrasound tests. Ultrasound power was gradually increased from the lowest setting (−30 dB, MI = 0.05) to the highest (0 dB, MI = 1.1) and then cycled back to the lowest again at an average rate of 1 dB/s.
