Typical pulse-diameter plot of a single microbubble (DSPC:DSPE-PEG2000) undergoing acoustic dissolution at 2.25 MHz, 400 kPa PNP, 0.5 Hz PRF. Measurements are shown as scatter, and sigmoid curve fit is shown as solid line. Sigmoid behavior exhibits the following three regimes: slow acoustic dissolution at large diameters; linear regime, with a constant acoustic dissolution rate at intermediate diameters; stable microbubble regime for which size does not change over many pulses.
