The Optison attenuation coefficient exhibits a single peak between 1 and 3 MHz. The exact peak location, height and width vary significantly with experimental conditions. In contrast, the PFOB emulsion does not exhibit any of these effects, which strongly shows that microbubble formation through perfluorocarbon phase conversion may not contribute in a measurable manner to the acoustic properties of the liquid perfluorocarbon nanoparticle contrast agent over the range of experimental parameters considered.
