Acoustical characterization of submicron particles of perfluorocarbon in solution [ultrasound targeted contrast agent]

Determining the acoustical properties of submicron particles of perfluorocarbon in solution is important to explain their response to ultrasound pulses when bound to a target. In this study, we present measurements of the frequency-dependent attenuation at different particle sizes, pressures and bandwidths. Backscattering spectra of the particles probed… CONTINUE READING
