Physical Characterization of Microbubble Based Ultrasound Contrast Agents

During the past few years the application of microbubbles in the lower micron range as ultrasonic contrast agent has become more and more interesting. This is due to the fact that microbubble based contrast agents became commercially available and that progress was made concerning some of the main problems for the use of microbubbles as contrast agents, for example bubble size and bubble lifetime.
