Composition and initial resting diameter dependence of acoustic dissolution parameters at 2.25 MHz, 400 kPa PNP, 0.5 Hz PRF. (a) Stable diameter and (b) acoustic dissolution rate of linear regime versus initial resting diameter. Data shown for microbubbles coated with the three phospholipid chain lengths with the lipopolymer emulsifier (i.e., DMPC:DMPE-PEG2000, DSPC:DSPE-PEG2000, and DBPC:DSPE-PEG2000).
