Abstract

The analysis of the dynamical response of gas filled cavities surrounded by elastic capsules, acting as contrast agent microbubbles, is of importance in elucidating their full diagnostic use for ultrasound imaging. When the frequency of the external acoustic field is at or near the natural frequency of the bubble, resulting in resonance, larger amplitudes of oscillation than would otherwise occur are observed, enhancing the backscattered signal. It is therefore important to medical ultrasound imaging to be able to accurately determine the complex resonant behaviour of the bubble motion.
