Broadband Attenuation Measurements of Phospholipid-Shelled Ultrasound Contrast Agents

Abstract The aim of this study was to characterize the frequency-dependent acoustic attenuation of three phospholipid-shelled ultrasound contrast agents (UCAs): Definity, MicroMarker and echogenic liposomes. A broadband through-transmission technique allowed for measurement over 2 to 25 MHz with a s...
