From: Multi-focal HIFU reduces cavitation in mild-hyperthermia
Distribution of measured cavitation activity (summed channel variance), vs. total power applied to the array for one set of sonications at 5, 10, 20, 40, 60, 80 W. Box locations are offset along the x-axis to allow side-by-side comparison. Each box represents the distribution (min-max, and 25, 50, 75th percentiles) of cavitation activity. a and c, distribution within the first second. b and d, distribution over the full 30-seconds
